Energy Efficient Heating Systems and Renewable Energy Solutions in Dorset

When designing heating systems for our Dorset and Hampshire clients, our first step is to calculate any heat losses along with the demand for hot water. The higher the insulation standard, the lower the heating requirement of the building.

A heating system design is based on standard worst case scenario. This means full demand on the system with an outside air temperature of approximately minus 2 degrees centigrade. However, these conditions only prevail on perhaps 8 days a year. The rest of the time a large capacity boiler is not working efficiently.

Combined Renewable Heating Systems

Combined hot water and heating systems involve using two or more different heat sources.

For example, solar  panels can provide most of the domestic hot water requirements for a family home throughout the summer months – with barely a sign of a carbon footprint.  A heat pump or traditional boiler can cover the demand for the remainder of the year. An air source heat pump is an extremely efficient way of producing hot water for both domestic use and central heating.

Having control of renewable heating systems is of the utmost importance for gaining maximum efficiency and the lowest carbon footprint. Present on most air source heat pumps is the addition of sophisticated weather compensation to the controls.

Underfloor Heating

With modern underfloor heating systems you have complete room temperature control.

Benefits of Underfloor Heating Systems

  • There are no cumbersome radiators occupying valuable floor space
  • Fuel bills are lower due to lower water temperatures and comfortable warmth for all your heating needs
  • Warm dry floors create a hostile environment for dust mites
  • Underfloor heating also reduces the danger of damp and condensation getting into walls
  • The low amount of air movement during heat transmission will also help prevent airborne dust.

Underfloor Heating Systems – How Do They Work?

Water circulates through the underfloor heating pipes at around 40C (approx. 70C through a radiator system). This in turn heats the floor to a surface temperature of 25 – 28C. These systems are economical to run, virtually maintenance free and provide the most comfortable warmth consistently.

A typical ground floor installation will involve laying insulation above the original concrete slab on insulation – all to ensure minimal heat losses. Fitted to this would be a flexible pipe with no joins within its length. Depending on your room layout, one of our trained engineers will decide how best to lay your pipes to optimise efficiency. Covering the pipes would be either a dry or liquid screed. To minimise heat losses and take up any expansion, a foam insulation strip is fitted around the edge of the room. Your choice of flooring will then be laid on top of this. If your project is not a typical installation then don’t fret as there are many ways to install under floor heating, the smallest being an overlay just 16mm thick.
