HEATING , VENTILATION & INSULATION
" These energy-efficient radiators also include an optimised heat exchanger , which uses 90 % less water than is used in standard radiators , meaning less energy is needed to heat the water up ."
DO I NEED BIGGER RADIATORS FOR A HEAT PUMP ?
Not necessarily . If sticking with conventional steel panels then unfortunately these will need to be either longer or deeper , but there are alternatives out there such as the energy-efficient options , which use the lower flow temperatures of a heat pump better so there is less need to lose wall space for the sake of going greener . The energy-efficient options are typically made from materials with high thermal conductivity , such as aluminium .
COULD I USE MY EXISTING RADIATORS ?
This will depend on a number of factors including the size of your home and how insulated it is . It is probably best to check with an authorised installer , but it is quite likely you will need to upgrade your radiators to compensate for the lower flow temperatures that heat pumps operate at .
