Gas Ecogen Boiler

The Baxi Ecogen dual energy system (Micro-CHP)

Gas Ecogen Boiler

Advanced Green Energy provides a comprehensive solar thermal service which uses the sun’s warmth to heat some of your hot water.

How does it work?

Solar panels on your roof contain fluid, which absorbs irradiance from the sun. This is then pumped through pipes to your hot water cylinder which heats the water to a preset temperature. Your boiler or heater then uses this to top up the heat as required, so you can enjoy peace of mind that you’re saving money every time you run a hot bath

Solar thermal systems run best in summer months, when they can heat up to 90% of your hot water. However, you’ll still save money all-year-round.

How we do it

We offer two types of solar thermal panels: high efficiency evacuated tube solar panels and high efficiency flat plate solar panels. Both offer a range of similar benefits and we will be happy to discuss the best product to suit your needs.

Financial Income

Micro-CHP is eligible for Feed-in Tariffs and you will earn 11.0p for each kWh of electricity generated by your system. You will also receive 3.2p for each kWh of electricity you export. Feed-in-Tariffs are Tax free and inflation linked. The Feed-in Tariff is paid over a minimum period of 10 years from the date the installation is first registered.

Installation Is Easy

For the householder, there is very little difference between a micro-CHP installation and a standard boiler. If you already have a conventional boiler then a micro-CHP unit should be able to replace it as it’s roughly the same size. However, the installer must be approved under the Microgeneration Certification Scheme.

Generating electricity for your home

The Baxi Ecogen micro-CHP boiler produces up to 1kWh of electricity, that can be used throughout your home. But just how powerful is 1kW?

What can 1kW power?

  • 10 20W light bulbs (0.2kW)
  • TV (0.1kW)Computer (0.1kW)
  • Washing machine (0.6kW)
  • All of these combined = 1kW

Maximum cost savings can be achieved by using the electricity from the Baxi Ecogen as you generate it. For example, you could do your washing or ironing in the evening when your heating is on.

Gas Boilers

Boilers account for around 60% of what you spend in a year on energy bills, so an efficient boiler makes a big diffrence.

Replacing an old boiler with an A-rated high-efficiency condensing boiler and improving your heating controls will significantly cut your home’s carbon dioxide emissions and could save you as much as £300 per year.


Combination Boilers

A combi (or combination) boiler is great for saving space and is also a popular choice with customers. A combi boiler is both a high-efficiency water heater and a central heating boiler, combined within one compact unit. Therefore, no separate hot water cylinder is required, offering space saving within the property.

Further benefits of a combi boiler are significant savings on hot water costs and the fact that hot water is delivered through your taps or shower at mains pressure. So you can enjoy powerful showering without the need for a pump (mains pressure would be tested).

Another benefit is that it can save you money on installation time and costs, since no tank in the roof space means less pipe work and a shorter installation time.

Regular Boilers

Regular boilers heat your central heating system directly and produce hot water for your cylinder. If you are replacing an older model of boiler, the chances are that you will have a regular boiler (also known as a conventional boiler).
A typical regular boiler system incorporates a boiler, extended controls, a hot water cylinder which is often fed by a cold water storage cistern located in the loft and a feed and expansion cistern – also located in the loft.

System Boilers

A system boiler heats your central heating system directly and produces hot water for your cylinder. A system boiler, just like a regular boiler, however a system boiler differs from a regular boiler in some important respects.

Firstly, many of the major individual components of the heating and hot water system are built into a system boiler, which means that installation is quicker, neater, easier and more efficient.

System boilers heat radiators and hot water cylinders quicker due to the heating system being a sealed system (under pressure) and more economical running costs.

The system boiler removes the need for a feed and expansion cistern.

System Boiler and a Hot Water Cylinder

This is an example (bottom images) of using a system boiler and a pressurised unvented hot water cylinder. This type of system gets rid of the need for any tanks being in the loft.

The cylinder is fed by the incoming mains water instead of a tank. Hot water is delivered through your taps or shower at mains pressure, so you can enjoy powerful showering without the need for a pump. Also you can run the hot tap quicker without the water being cooler unlike a combi boiler. This type of hot water cylinder is very highly effecient.
