Recommend installer ASHP Manchester

[Wadrian]

Hi

 

we are doing a self build in Manchester and are opting for ASHP. Is it better to have the ASHP in a ‘separate plant’ room away from house or stick it on the side of the house (noise for neighbours). What is impact on costs and efficiency of system on where you site the unit.

Can anyone recommend a good MCS installer for ASHP that could install in Manchester?

 

thank you

I’m just down the road from you near Preston 

We are on a HP We’ve been down to -8 and the HP coped fine 

Many of the guys on here are up in Scotland and experience much lower temps on a far more regular basis So probably better placed to advise on that one 

 

We used a local small company That are second to none [phone number deleted by mods and forwarded to original poster]

Thank you for recommendation

On this map you can get a good idea of who at least fits efficient systems in your area

Really almost no impact on efficiency if sited away from house, within reason. 5 to 10m is fine, over that needs some thinking about. The ASHP will not be 'in' a plant room it will be outside, always. Noise is down to assessment by your installer, he will approve it not location based on an assessment.

 

Distance from house wall will add cost as you will need to trench in insulated pipes.

 

I would really look at the cost premium you pay for an MCS install and assess if it's actually worth it. Also look at MCS umbrella schemes.

I have heard that MCS installers may simply bump up the price to take account of the grant - is that what you are saying in your last point?

Yep.

 

Your solution should look like

1. ASHP sized for heat demand at approx -3. Between £2.5 and stupid money. A good Panasonic is nearer £2.5k

2. A 3 port diverter valve, generally come with cylinder.

3. A heat pump specific cylinder the bigger the heat transfer coil the better the CoP you get while heating the cylinder. Circa £1k depending on size.

4. Ideally UFH on a single zone, so need for mixer, pump or actuators on manifold. Or a conventional radiator system sized to run at a low a temperature possible.

 

Options - should come free with the correct heap pump.

Cooling, UFH will take the extreme over temperature away, and reduce recovery time dramatically, coupled with PV costs nothing to run. Radiators don't do cooling.

 

If UFH and they insist on buffers or volumiser find a new installer.

 

If you are reasonably well insulated and decent airtightness a 6kW heat pump should be fine for around 300m² house. Anything bigger start digging to find out why.

It’s true 

We paid 5k after the grant for cylinder 11kW HP Pumps UFH second fix and stats 

Other will tell you different But I couldn’t buy the materials in at 5k 

Im on my second self build and pretty good at keeping in budget
