How to Evaluate Your Boiler Installer?
There are several factors to think about when trying to decipher between competing boiler installers. Here are some of the essential aspects you should take into account when making your decision.
Gas Safe Registration
First and foremost, you need to choose a Gas Safe registered company and engineer. Boilers can go horribly wrong if installed by an unqualified boiler installer due to potential carbon monoxide poisoning. Therefore, the heating engineer you employ for your new boiler installation must have the Gas Safe certification to prove they know what they’re doing.
Industry Accreditations and Approved Installer Status
Look for professional and industry accreditations to prove that your chosen provider is committed to their trade and providing a good service. City and Guilds qualifications are a good sign, as are companies with a Which? Trusted Trader status. You should also ensure that your installer is approved by major boiler brands, as this is a sign that they are trusted to carry out work on behalf of the manufacturer.
Free, No-Obligation Quotes from Heating Engineers, Not Salesmen
There are plenty of excellent boiler installation companies out there. But unfortunately, some of them prefer to send salespeople to perform home visits rather than qualified heating engineers. There are two problems with this. Firstly, sales associates aren’t qualified to assess your boiler and heating system. Secondly, they often receive a percentage of each job they win.
What this means for you is that you could be quoted and pushed into the wrong type of boiler for your home. For instance, you may be quoted for a conventional boiler system when a combi boiler would be a more cost-effective solution. Worse, you could be charged for unnecessary additional work that drives the price of installation up without adding any value to you, your boiler, or your home.
On a visit to inspect your current arrangements, you should look to deal with qualified gas and heating engineers who provide you with a free, no-obligation quote. You shouldn’t be pushed into accepting any price under the pressure of sales tactics.

Solar water heater is used to heat water by using sunlight. It mainly consists of:
1.A thermal panel (solar collector) which is installed on the roof.
2.A tank used to store hot water.
3.Circulating pump to carry the solar energy from the collector to the tank, and a thermal regulator.
Solar water heaters come in a wide variety of designs.
Working of a Solar Water Heater
The solar water heater absorbs light by means of a collector placed on the roof and converts it into heat. It passes this heat to a water tank by means of a circulating pump. This exchange is triggered by the thermal regulator, but only when the collector is hotter than the water in the tank. This prevents the circulating pumps using electricity needlessly. Conversely, it also prevents overheating.
The efficiency of the collectors is at its highest at midday, in summer, when the sky is cloudless, and when the collectors face south.
When there is insufficient sunlight, the water is preheated and a back-up system takes over to bring the water to the required temperature. This system can therefore be used to produce hot water at a constant temperature throughout the year without emitting any CO2.
Solar water heaters are typically described according to the type of collector and the circulation system.
Batch collectors, also called Integrated Collector-Storage (ICS) systems, heat water in tanks .Water can remain in the collector for long periods of time making it very hot if household demand is low. A tempering valve is there for protection from scalding at the tap. It mixes in cold water to decrease the water’s temperature before it’s delivered to the tap. Batch collectors are incompatible with closed-loop circulation systems. They are generally not used in cold climates.
Flat-plate collectors consist of copper tubes fitted to flat absorber plates. The most common configuration is a series of parallel tubes connected at each end by two pipes, the inlet and outlet manifolds. The flat plate assembly is contained within an insulated box and covered with tempered glass.
Evacuated tube collectors are the most efficient collectors available. A glass or metal tube containing the water or heat transfer fluid is surrounded by a larger glass tube. The space between them is a vacuum, so very little heat is lost from the fluid.
Direct systems circulate water through solar collectors where it is heated by the sun. The heated water is then stored in a tank, sent to a tankless water heater, or used directly.
Closed-loop, or indirect, systems use a non-freezing liquid to transfer heat from the sun to water in a storage tank. The sun’s thermal energy heats the fluid in the solar collectors. Then, this fluid passes through a heat exchanger in the storage tank, transferring the heat to the water. The non-freezing fluid then cycles back to the collectors.
Active, or forced-circulation, systems use electric pumps, valves and controllers to move water from the collectors to the storage tank.
Passive systems require no pumps. Natural convection moves water from the collectors to the storage tank as it heats up.

Heating water is very expensive, as it requires a huge amount of energy. It is believed that 18% of domestic energy is used to heat water. In most homes and businesses, this energy is generated from fossil fuels — gas and oil. Most modern domestic boilers will run on gas and heat water on demand. Nevertheless, many people still heat their water using electricity, which is the most expensive way to heat water.
Over the past several decades, different solar water heater manufacturers, ranging from correlation-based methods to simulation-based methods such as transient system simulation, have developed a number of design methods for solar water heating systems. In recent years solar water heater manufacturers uses some design methods by optimization techniques such as linear and nonlinear optimization and evolutionary algorithms have been proposed. These optimization-based methods are conceptually different from traditional correlation- and simulation-based methods in terms of the process of finding the optimal design.
The proposed multi-objective optimization method is developed to determine the optimal design of an indirect forced-circulation solar water heating system based on the minimization of the Life cycle cost and maximization of the life cycle net energy saving. To obtain an efficient and reasonable design, installation- and operation-related design variables as well as capacity-related design variables are optimized. The sizes of the main components except for the heat exchanger and storage tank, whose quantity is fixed as one, are computed using their quantity and unit capacity. The unit capacities of each component are recognized according to the device types, which are expressed as the identification number assigned in regular sequence in the inputted data tables.

Incentive and Tax Benefit from the state and federal government
Whether you use evacuated tube or flat plate solar water heating system, you can earn the state and federal government’s RHI and tax benefits. Under this plan you are given payments for using solar heating technology continuously for years.
Considerations for solar water heating systems
Right location for Solar panel
You should have at least a flat space on your roof of 5 meters facing east to west and getting sunlight directly throughout the day. This is the best place where you need to place the solar panel for optimal performance. If it is not available then you can consider attaching two different panels facing east and west respectively, which would add to your installation cost.
Addition/replacement of hot water tank or cylinder
Another key consideration is to find space to keep an additional hot water cylinder in the home or office. While installing solar water heating system, you will have to either replace the present cylinder attached to the solar heating coil or add a new cylinder to keep up its heating performance.
Compatibility of Boiler
You need to find out about the compatibility of the present boiler with the solar thermal system. Combination boilers don’t usually have a hot water cylinder and may not always be compatible with the solar thermal system.
Permission and approval from local building regulations
While fitting solar PV panels on the roof of your building you may face some issues in building codes. Therefore, it is better to have approval from local building regulatory authorities to make sure that you meet the building codes and can move ahead with the installation of a solar water heater.

The development with solar energy is as controversial as ever; but one thing you can’t deny that it’s getting more efficient and affordable with every passing year. Solar energy has become a main source of household energy supplier and effective for a homeowner. One of these steps is implementing the technology of solar water heating systems.
The Working Principle of Solar Water Heaters
Solar water heating systems heats the water directly that gets pumped into your home. There are two main types of solar water heaters available on the market, active and passive. Both types can depend on the climate. Therefore, it’s highly recommended to try them during the warmed months of the year.
Active solar water heating systems utilize pumps for water circulation through pipes located in the solar panels. Passive solar water heaters use a storage tank and solar collection tank where hot water can be kept for use later.
The Significance of Solar Water Heaters
Clean and highly efficient water heating
Solar energy is free and abundant. It has no carbon footprint. If you want to get away from hydro and gas power, solar water heater is a perfect option. It is perfect for those who live in an area that receives a lot of sunshine as approximately 80% of the radiation is converted into heat energy.
Great return on investment
Though solar power needs an initial investment to install, it replaces the energy you would be buying from the power company. Depending on the location, the investment will offer electricity savings. It’s estimated that your water heating bill would be minimized up to 80% with a solar water heating system.
Easy to maintain and operate
The solar water heaters don’t need much maintenance. All you need to do is to circulate a water softener in the pipes during every 3 years.
There are few moving parts in solar water heaters; but in general the system doesn’t produce much noise.
Unlike other solar technology that required the installation of 16 solar panels, the solar water heater requires two or three. You’ll require some additional space for the storage tank if you’re utilizing the passive process, but other than that it doesn’t take up enough space.
Renewable heat benefits

The development of green energy is as controversial as ever, but one thing you can’t deny is that — green energy is getting more and more efficient, and more affordable with every passing year. One of the main uses of this energy is implementing the technology of a solar water heating system.
Generally, solar water heaters require less maintenance. However, it’s necessary to check your solar water heater at least once a year to ensure all components are in top condition and to keep the system working perfectly.
Some of the components of solar water heating systems that should be monitored include:
1. Solar Collectors –
Solar collectors should remain un-shaded. It’s really common for solar panels that were in complete sun exposure when they are installed to receive shading due to tree growth. You may need to trim or remove vegetation.
Many states have their solar laws and regulations that protect the rights of a solar homeowner to maintain the solar accessibility for existing systems.
Dirt and dust particles can impact on the performance of collector. During dry, dusty weather condition, the solar panels may require cleaning periodically. Usually, snow and ice melt off on their own , but may require to be removed during heavy accumulations, if the panels are mounted at a shallow angle.
The solar collectors should be checked for yellowing or cracks. The seals can be checked to make sure they are still in good condition.
2. Roof and support
Roof penetration should be checked on an annual basis to be sure there are no issues with water leakage. Both the nuts and bolts on racking systems should be inspected for tightness as well as racks are checked for signs of stress.
It’s really necessary that the pump should remain in good condition as the pump failure can cause the solar water heating systems to overheat. The cold supply, high-pitched noises, return pipes are the best possible signs of a pump failure. If you find the pump is compromised, it should be repaired or replaced right away.
4. Controllers and sensors
Both the sensors and controllers are the main part of the control system for your water heat. So it’s important that they should function properly. To check a sensor, apply mild heat. Remember, it should record the rise in temperature.
Many controllers come with digital displays that indicate malfunctions. However, you should check the unit by triggering differential — the temperature difference that the system is programmed. You can do this by apply heath and cold to the sensors until the system reacts.
5. Heat transfer fluids
Most solar water heating systems use a glycol solution. You should check the fluid annually to make sure it’s in good condition and should be replaced, if required. If you keep the system in a hard water area, the fluid should be treated to prevent scale.
6. Hot water storage tank
Hot water storage tank should be checked periodically for corrosion, leaks, or cracks.
While many of the parts can be checked by the user, some of them are best performed by a solar expert. Visit solar water heater maintenance dubai to know more information about solar water heating systems!

To cut down your annual energy bills & carbon footprint installing a solar water heating system for your home is the best thing you can do. And now Government offering incentives to people that are installing renewable technology in their home, there couldn’t be a better time to getting one fitted in your home as well.
However, there are quite a few things you need to ask yourself before installing a solar water heater system for your home. Let’s find out what are they:
Is your home suitable for installing a solar water heating system?
A typical heating system needs a panel to be fixed to your roof to gather heat from the sun. To maximize the effect you require a 3–4m² area on a South-facing roof that gets direct sunlight for the most part of the day. A South-West and South-East facing roof can also be considered but won’t work as effectively.
Flat plate or evacuated tube systems?
Well, solar evacuated tubes are known to be more competent in covering sun rays into heat compared to flat plate panels. However, issues may arise during set up if they’ve not been correctly sized.
Nevertheless, flat plate solar panels are an affordable substitute to evacuated tubes & are more suited for residential hot water use.
Or you can use flat plate panels and solar evacuated tubes collectively. The flat plate warms the water first, then the evacuated tube further amplify the temperature prior to sending it to the storage container.
Do you require planning approval for installing a solar water heating unit?
Changes to authorized development consent for renewable technologies have made it really simpler to set up solar panels on residential properties without the need for planning approval.
However, the special case does apply for conservation areas, listing buildings and areas of exceptional natural splendor.
Regardless of where you’re, if you’re thinking about installing solar heating it’s recommended to check with your local authority if planning approval is needed before the installation process.
Is your existing boiler compatible with solar water heating?
The good thing is that most traditional boiler systems & hot water cylinder systems are compatible with solar heating. However, if you have a combination boiler that runs without a tank then it’s expected that it won’t be compatible. If you’re not sure it’s wise to consult a competent installer who can guide on compatibility with your existing system.
