Heating System Design and Installation.
It’s essential to pay particular attention to detail and consider all variables when designing a heating system. In order to achieve optimum efficiency the system should be designed to heat the building to the specified internal design temperature on the average coldest day of the year, otherwise known as the external design temperature. The system should be designed to use the lowest flow temperature possible to minimise the energy required at the heat source to heat the building.
Underfloor heating is undoubtably a perfect match for most heat pump and low temperature heating systems. Constant low grade energy provides a consistent comfortable temperature throughout all year. Underfloor heating can be installed retrospectively in buildings using suspended timber floors or a concrete slab, the latter being the preferred choice as the concrete is usually insulated below and used as a large thermal mass to store energy provided by the underfloor heating system.
A common misconception is that existing radiators need to be doubled in size in order to work with a heat pump. This is not normally the case as the existing radiators are likely to be oversized due to rule of thumb methods used by traditional heating engineers and also the upgrading of insulation, windows and doors has lowered heat losses in buildings throughout the UK.
