Air Source Heat Pumps

ra200

This might be worth a watch

Phil Hurley, the Managing Director of NIBE Energy Systems, will be discussing how its Heat Pumps operate and the money saving advantages which can be obtained by installing any one of its units on a new TV series on "How to Reduce Energy Consumption and Save Money" which will be showing on Sky Channel 201 and Freesat Channel 403 on Tuesday 8th March at 7:30pm and repeated on 13th March at 6:00pm.
It is hoped that this new eight part series will encourage Britain's homeowners to explore new ways of saving money and reduce their carbon footprint. The first two episodes will explore how the average household can reduce its bills by as much as £225 per year, together with practical support and how to appy for financial support.
This new series is expected to attract 22 million views in over 9 million homes in the UK. These programmes are accessibly to any Sky subscribers and are also accessible to "Free to air" channels.

I've just been quoted £23500 for an ASHP...
What size? Do you live a mansion?

Money saving eh...? for who exactly...?

It would be cheaper moving to a hotter country

Someone is taking the mickey, as that looks more like a very large GSHP installl!!!!

Hi - been reading through this forum, and was hoping to get some 'expert' opinions on this set-up;

House of 100m2, thick stone walls, but lined and well insulated.

Currently on LPG - very high fuel cost, just keeps going up.

Underfloor heating plus a few rads.

Looking at an SDEEC heatpump RM55 10 (French military manufacturer, sdeec.fr)

It's 9.5kW, and has a COP of 4.3. Can go up to 55'C, but we only need 40 or so. Even at -5'C the COP is quoted as better than 3.

The house is close to the sea, and this HP has a stainless casing and stainless heat exchanger. No DC inverter, as apparently a 'potential weak point'.

Already have an electric immersion for hot water, so this will just do the heating.

For simplicity, rads and underfloor are at same temperature.

The quote is at 8800 Euros (we are in France) (7800£ ish) installed, with 200 litre buffer tank. Doesn't strike me as too bad.

To get hot water too, would need bigger tanks, more plumbing etc. and the quote jumps to 12500. Not worth it IMHO.

Any feedback on this? Cheap, expensive? Thankyou!

Spec seems good. I don't know anything on the make, but may be worth asking if you can contact any other customers for their opinions.

Looks like a good price to me.

The DHW tank could cost around E2000+ so plus the other work could push up the cost to that level. If you are happy with just the immersion, then stay with it.

Hope this helps

Hi, this is my first post - hope somebody can advise me

I intend to have a ASHP installed in August. My 185sqm detached bungalow was built in 2005 has blown polystyrene bead cavity wall insulation and 200m fibre in the roofspace. It has room zoned UFH

I am located in northern ireland - no RHI yet but it is promised!!!!

I have been quoted by 2 firms, one advising a 16Kw Altherma monobloc and the other a 14Kw Ecodan. The price difference between the 2 quotes is £200

Does the sizing seem ok and which one do you think I should go for

Cheers

Sounds like your house will be well insulated since it was only built in 2005. Also given that you already have underfloor heating it will be perfect for a heat pump.

I would prob go for the 16kw system... Extra duty is always welcome in a worse case scenario.

Both are good manufacturers. Which was more expensive?

pyabsley

Thanks for your reply

The Altherma system was £200 more expensive but this could be down to different types of fitting and labour costs not the eactual pump

richardc1983

Have you made your choice?

pyabsley

Leaning towards the Ecodan at present

Just had electricty company fitting a voltage meter to see if the supply is adaquate, they will be back in a week to take the readings - fingers crossed

Should really go for max 10% undersize for best operating and money saving.
