ASHP and building load

[markfxy]

I would recommend the sanyo air source heat pump it uses CO2 as a refrigerant and can give higher water temperatures than the Daikin or Mitsi CO2 ECO Overview - SANYO EMEA

Tank Unit - SANYO EMEA nice, it comes with a nice 9kw back up immersion heater for every day use and another 6kw immersion back up for when it get cold?????? £££££££££$$$$$$$$$££££££££
Earth save products dont use immersions.

earthsave products do use immersions the immersions in the sanyo are purely for emergency backup not for everyday use. The earth save heat pumps are just cheap chinese unbranded products bought off the alibaba.com website

No they dont.
No there not.

Hi

I'm interested in these new-fangled Air Source Heat Pumps for my house but I understand you need to calculate the building load for the house to be able to size it correctly. Anyone got any pointers as to the best way to do this? I expect it's really complex and you need to get a 'consultant' in who will charge a fortune for doing some work on a computer! Pointers to avoid the 'consultant' would be good

Cheers

You think the consultant is going to be expensive? Wait until you get the full quote for the heat pump! You need to get a company in to do a SAP rating of your house which might not be as expensive as you think, you need to get that part of it right as if you size the pump up to small it will not meet your heating / hot water demands for your house and size it up too large and you will pay higher electric bills.

I have had dealings with so-called consultants and you would be better off just dealing with a decent Heating engineer

Would add the hitachi yutaki units as well. I've been impressed so far. Also done the simplex training and now accredited with them and Viessman both good looking units apart from Viessmann is massive

Not heard of a simplex heat pump? where are they based?
