HYBRID HEATING
THE RIGHT MIX Steve Calvert partnered a Grant solar thermal system and thermal store with a VortexBlue oil boiler on a recent project in Wales. PHPI reports.
A
large property in Llanfyrnach, Pembrokeshire underwent a complete refurbishment and the home’s heating and hot water requirements are now being met more sustainably by a bespoke hybrid system consisting of a Grant solar thermal system installed alongside a VortexBlue oil boiler. With the size of the property increasing to a six bedroom house, a brand new heating system was required to meet the larger heating and hot water demand of the home. Prior to the renovation, the property was heated by a non-condensing oil boiler so the homeowner wanted a direct boiler replacement which operated more efficiently and incorporated cleaner burning technology. After discussing the options available with the installing engineer, S Calvert Plumbing & Heating, a Grant VortexBlue Internal 26kW condensing oil boiler was selected for the installation. This utility model, which can achieve efficiencies of up to 91.71%, is white cased which makes it a sleek option to suit either a kitchen or utility room environment. For this installation, the boiler has been sited in the utility room. In addition to the oil boiler, two other products from Grant’s product portfolio were installed. A Grant solar thermal system was fitted which comprises two flat plate collectors. The collectors have been installed as part of an in-roof mounting arrangement allowing for a low-profile appearance. Grant’s in-roof mounting option comprises the collectors being set into the roof tiles, naturally following the roof’s angle to capture maximum energy from the sun. The solar thermal system at this property has been connected to a Grant ThermaWave 400ltr thermal store. These
