Further Information & Advice

Solar thermal evacuated tube collectors can provide a percentage of your domestic hot water needs, the remaining shortfall is made up by your traditional gas boiler (or other heating system). An evacuated tube collector system is made up of the following main components: Solar evacuated tube collector(s), twin coil water cylinder, traditional boiler, pump station and control.

Vokèra advises that a solar evacuated tube system is connected to a twin coil cylinder and a system or open vent boiler. This allows the solar energy collected to be stored in a cylinder for later use, the boiler also acts as a top up, when the solar evacuated tube collector does not reach the desired temperature. Current regulations are unclear as to the usage of solar thermal installations with combi boilers. We will update this page upon clarification of the guidelines.

Vokèra solar flat plate collector systems are made up of the following main components: solar flat plate collector(s), pump station, control, twin coil water cylinder and traditional boiler. The solar system will provide a percentage of the domestic hot water requirement, the boiler then steps in to make up the differential.

We recommend that a solar flat plate collector system is connected system or open vent boiler and a twin coil cylinder. This allows the solar energy collected to be stored in a cylinder for later use and the boiler provides a top up in temperature, when the solar collector does not reach the desired temperature of 60°. Current regulations are unclear as to the usage of Solar thermal installations with combi boilers. We will update this page upon clarification of the guidelines.

Renewable Energy

Renewables

Renewable energy technology has significantly progressed in recent years, making renewable energy products more financially accessible. There is a wide range of renewable energy products now available, including: solar heating, air source heating, ground source heating, biomass heating, combined heating and power.

All renewable energy products have their advantages and disadvantages, and you can find out more about the different technologies by clicking on the links. Some renewable energy products have a much quicker payback period than others and it will always depend on which fuel you are displacing. It is important to seek advice from the manufacturer or qualified engineer on renewable energies to establish what energy savings are achievable for your individual circumstances.

Vokèra offer the following Renewable Energy Products:

Open Vent Boiler

Open Vent Boilers

An open vent boiler is a boiler that is installed on an open vent central heating system, the term open vent, relates to the heating system being open to atmospheric pressure, as major components to the open vent system includes feed and expansion tanks in the loft space. An open vent boiler heats the radiators and, via a storage cylinder, the domestic hot water.

An open vent boiler is also known as a conventional or regular boiler. If you currently have an open vent boiler in your property, it can be more straightforward to have a direct replacement, unless your property or lifestyle has changed. Open vent boilers are also compatible with solar thermal, therefore if you currently have an open vent boiler, adding a Solar thermal system can be fairly straightforward. Always seek advice from your Gas Safe Registered engineer.

Model Name Description
Mynute VHE Compact and flexible open vent boiler

An open vent boiler is an ideal boiler if:
  •  You want to replace an existing open vent boiler and are happy with the performance your open vent boiler provides
  •  You have more than one bathroom in your property
  •  Your mains water pressure is low

System Boiler

System Boilers

A system boiler is a boiler that is installed on a sealed central heating system, as the word suggests it is not open to atmospheric pressure and the system is kept with a closed circuit.

In this type of heating system, a system boiler connects to a storage cylinder that provides the domestic hot water. As the heating system is sealed it requires no tank in the loft space. When coupled with a mains pressure hot water storage cylinder (known as an invented cylinder), it is well suited to properties with multiple bathrooms. In this configuration, good flow rates can be maintained if more than one domestic hot water outlet is in use at the same time. System boilers are also compatible with solar thermal, therefore if you currently have a system boiler, adding a solar thermal system can be fairly straightforward. Always seek advice from your Gas Safe Registered engineer.

A system boiler is an ideal boiler if:

  •  You want to replace an existing system boiler and are happy with the performance your system boiler provides
  •  You have more than one bathroom in your property
  •  Your mains water pressure is low
  •  You have a regular boiler and you want to remove the feed and expansion tanks in your loft space

Gas Boilers

Boilers

All Vokèra boilers are condensing, or high efficiency, boilers as it is also known which maximise the heat the boiler generates by recovering some of the lost energy, which would normally be lost through the flue.

A condensing boiler can on average save you 30% of your energy usage. Legislation that came into force in 2005 now requires that any new domestic gas appliance is a condensing boiler.

In 2015, a piece of mandatory legislation was introduced that requires the presence of energy labels on heating products and systems.

There are three main types of condensing boilers:

Combi Boilers

A combi boiler, also known as a combination boiler provides heat for central heating and domestic hot water upon demand. With a combi boiler heating system you do not require feed and expansion tanks in your loft space or a storage cylinder, therefore saving space. Read more here >>

System Boilers

A system boiler is a boiler that is installed on a sealed central heating system, as the word suggests it is not open to atmospheric pressure. In this type of heating system, a system boiler connects to a storage cylinder that provides the domestic hot water and central heating. Read more here >>
