For 29 years we used thermostatically controlled storage heaters and since our bungalow is airtight and very well insulated, the running costs of storage heating was reasonable.
However, in 2018, we removed all the storage heaters and had a 7.5kW air-sourced heat pump fitted driving two cassettes and a wall unit.
We used this system for the 2018-19 winter with two cassettes in the main hall, but they were not quite sufficient to heat our bungalow.
So, in 2019, we had an additional 5kW air-sourced heat pump fitted to heat and cool the lounge and provide additional heating to the bedroom area.
We had tried a stand-alone portable air-conditioner, but it was incredibly noisy and needed a huge snakey hose.
Our current ventilation system had served us well, but significant technological improvements had taken place in the past 20 years with new models having more efficient heat recovery and having optional air sourced heat pumps that can provide heating in winter and cooling in summer meant it was time for an upgrade. Newer models also have better efficiency, air filtering, control facilities and monitoring.
