94% of UK Homeowners with heat pumps are satisfied with their heating. Yet social media is packed with claims that they don’t work in old houses, are expensive to run and are noisy. What’s the truth?

So many houses in my street with windows open trying to cool down. But if it’s hotter outside than in this isn’t going to work! Dump heat morning and evening, and then keep everything shut for the rest of the day. Graph shows I wasn’t fast enough off the mark this morning! #EcoBungalow #Passivhaus

The MVHR either warms incoming air through the heat exchanger or brings it in at outside temp, bypassing the exchanger. Doing something clever today. Bypass is fully shut (so heat exchanger operating), incoming air ever so slightly cooler. Never seen this before. #EcoBungalow #PassivHaus #Retrofit

Here's the Netatmo graph for air quality during November. You can see the high of 632ppm on PassivHaus Trust Open Day. Otherwise, it's been from 380ish to 560ish - pretty much consistently excellent. All thanks to the MVHR. #EcoBungalow #Passivhaus #PassiveHouse #EnerPHit #Retrofit #MVHR

What a contrast! One year ago we’d achieved the airtight line at ceiling and floor levels. But the internal wall insulation hadn’t started and the windows were yet to go in. Today it’s a light and airy yet cosy home. #EcoBungalow #enerphit #passivhaus #passivehouse #retrofit #airtightness

Staying in a flat with a gas combo boiler. After six months with an ASHP with a max temp of 45degC, heating water so hot you have to dilute it with loads of cold to wash up seems an utterly bonkers way to use energy. #EcoBungalow #passivhaus #ashp #retrofit #passivehouse #energyuse
