As Mike Foster, chief executive of the Energy and Utilities Alliance says ““Instead, they seem to be putting a Whitehall target for ripping out boilers for heat pumps as their priority. The interest of the consumer comes second best.” seems to be the typical case of the government these days.
There are no “heatpumps” on the market that continually operate at 40dB. Infact the majority operate alot louder:
Daikin Altherma 3: hight temperatue and Monobloc units 54-62dB
Nibe F2040: 50-61dB
Samsung’s Eco Heating: 58-75dB
Samsung’s TDM plus units (2 fans): upto 107dB
Vaillant aroTHERM: 54-60dB
Mitsubishi Ecodan: 57-69dB
LG Therma V: 77-69dB
Hitachi Yutaki: 61-74dB
Octopus don’t give a figure other than a heatpump is around 40-60dB.
60dB-level of sound in a typical restaurant dining area.
When you take into account the sound pressure emitted from the heatpump, sound power-theoretical measure of the sound the source emits, regardless where you are in relation to the source and the sound intensity-flow or direction of sound. You can imagine the sound generated in a typical housing estate if we all had one!
I have multisplit aircon with heat covering 4 rooms in my house that work off one outdoor unit (same as a heatpump out door unit) in an unused part of my driveway. It’s not quite in operation and heard by my neibour and from the road, even though its situated behind large double gates, its also far from cheap to run in the summer months when wetend to use it.
