All I say is, have you seen the price? Not exactly the cheaper ASHP on the market.

 

How many dBA? And at what distance?

[Nick Laslett]

If sound is your main priority this looks like an ASHP worth considering.

 

Spec sheet says:

 

Sound power level (EN 12102) = 48 dB(A)

 

The equivalent spec for my Panasonic WH-MDC05J3E5 is:

 

Sound power level (EN 12102) = 60 dB(A)

 

Vaillant aroTHERM plus 7kW

 

Sound power level (EN 12102) = 53 dB(A)

 

These are all at A7/W35

 

They seem especially pleased about the low noise and have made a video about it.

Obviously I have know idea what the below means 😂 but it does seem like it might be over kill for my two bed house in Devon !

 

 

 

WPL-A 07 HK 230 Premium

AIR SOURCE HEAT PUMPS PRODUCT-NO.: 200123

Create a pleasant climate all round

This air source heat pump doesn't just take care of your heating and hot

water. In the summer months, it can also provide cooling. And even at outside

temperatures as low as minus 25 °C, it achieves high flow temperatures for

pleasant room heating and high hot water convenience. This inverter appliance

therefore offers you a valuable service, no matter whether you are building a new

home or modernising an older one.

Doing the environment a good turn

The models in this series are set up to use a particularly futureproof refrigerant.

Combined with an excellent efficiency level, this heat pump raises your

environmental conscience in building services to a new high.

 

The main features

Air source heat pump installed outdoors for heating and cooling

Ideal for new build and modernisation

Inverter technology for high efficiency and low energy bills

Low noise emissions due to intelligent appliance design

Operating noise can be further reduced in night mode ("silent mode")

Highest energy efficiency even when using radiators

Optional integration into the home network and control via smartphone

(additional components required)

Flow temperatures of up to 75 °C for first rate hot water convenience

sound was one of the conditions that the planners were making a fuss about . They place a condition that I need to build an acoustic barrier between us and next door ( which can't be done as the barrier would need to be on the drive ) they insist on the drive to ensure we have off street parking etc etc . 

 

 

This is what they said :

 

Prior to first use of the air source heat pump (ASHP) hereby approved, an acoustic

barrier to the front of the ASHP will be provided and constructed to the following

specification:

A mass of 10 kg/m2, at a height where there is no line of sight from the ASHP to the

neighbouring bedroom window. It must be of solid construction with no air gaps. The

acoustic barrier shall thereafter remain in perpetuity unless otherwise agreed in writing

by the Local Planning Authority.

(Reason: To protect adjoining residents from noise in the interests of residential amenity

in accordance with Policy D1 - Design and Local Distinctiveness of the Adopted East

Devon Local Plan 2013-2031.)

In accordance with the requirements of Article 35 of the Town and Country Planning

(Development Management Procedure) (England) Order 2015 in determining this

application, East Devon District Council has worked positively with the applicant to ensure

that all relevant planning concerns have been appropriately resolved.

Etc...

Says nothing meaningful that doesn't really apply to most ASHP.

They don't really care if it's silent or the most noisy available - the same condition applies.
