HEATING, VENTILATION & SERVICES FOCUS INTERIORS


bathrooms if required. This heating and ventilating system is designed to be over 00 efficient in comparison to a gas boiler.


SUITABILITY Typical temperatures achievable for fresh filtered air when recycling heat with heat pump ventilation.


but not enough to warrant the cost and hassle of a formal heating system, an HPV system can deliver. Supplementary heat can be added in innovative approaches so that there is more individual room temperature control with a quick response. This can be through the filtered air in each habitable room, where a standard ceiling terminal is replaced with a heated ceiling terminal that supplies extra, self-regulated heat. Alternatively, the HPV system can supervise a radiant heating panel, to bring a comfortable room temperature up to a ‘cosy’ one!


Despite this, it may still be handy to have heated towel radiators in


bathrooms and WCs and perhaps a small wood burning stove or focal point fire in a sitting room.


HOT WATER Ventilation, space heating and cooling is all covered, without a large heat source, but how is hot water produced it there’s no boiler? An HPW air-to-water heat pump forms part of the system – a 300L cylinder with an integrated heat pump – to provide all domestic hot water requirements energy efficiently. It can heat about 1,000L of water a day and has a secondary coil to provide heating for up to 20 m² of wet underoor heating in a couple of


HPV (and HPW) systems are suited to homes that are to be built or retrofitted to Passivhaus/EnerPHit standards. However, the system may still be suitable if a home is well insulated and airtight with low U-values. To ensure that heat pump ventilation is right for an occupier and their home, an installer should complete a room- by-room heat loss calculation. For this, oorplans, sections and elevations together with the U-values associated with the envelope of the home need to be supplied.


For townhouses and apartments a compact service unit could do everything that the HPV and HPW units do, but in a more compact form. So while HRV/MVHR is great for ventilating a home without losing heat, is a ‘formal’ heating system required, with all the extra administration, installation time and trades on site, if a home is super-insulated and air-tight with a small overall heat loss? Or could heat pump ventilation be the whole house climate solution?

New dimension with interior steel doors SBH09_Dulux_Interiors - Paints_PR.indd 1


The owners of a large late-Victorian property in Surrey have completed the renovation and extension of their home by bringing style and light to the interiors through the installation of fully glazed steel-framed doors, supplied and installed by a member of the Steel Window Association (SWA). The contract was carried out by Godstone- based Govette Windows, a long term SWA member. The client, Adrian Lees Jones, commented: “Four of the doors are installed in the old part of the house rather than


the new additions, and we’ve just ordered a fi fth. The steel frames look completely different to timber or other alternatives, with slim sections, but have a really substantial feel, and they are very well made.”
