Dream heat pumps.

Simples really, you have two heat sources, one (the Air Source Heat Pump ASHP) is efficient so long as air temp above 5°C outside, so when it gets below that a simple control box based around a frost stat calls for heat from a traditional oil/gas boiler. - Just need to make sure of the hysterisis of the outside stat as you don't want the system cutting in / out every few minutes, so go for at least a 3°C temperature change before switching back to the Air Source Heat Pump - say off at 4°C and back on at 7°C.

Just remember guys anythings easy when you understand how it works but at the start of learning about anything its not always simple , just a thought eh whyme

Kris,

A bit of a waste of time up there, Scotland, solid rock and freezing most the time, solar thermal, well maybe now and then.....:dizzy2::cool3::sunny:

Cheers happy, air source can only really be used on its own on a new build up here which is fully insulated , on an existing building need secondary heat source but i dare say thats all over aswell eh, but i wouldnt fancy doin a bore whole in the granite city, need a mighty drill for that happy ,

Would have thought nice cosy log burners or pellet burners (aka biomass) ideal for the frozen off-grid wastes up there

Hi all I have a dream heat pump on my swimming pool 15 kW and to be honest it struggles to get to over the 29 degrees and now seems to have given up heating, I called dream ( who only deal through the e mail or you can leave a phone message and the may call you back after 3 days ( trick to this is keep calling every 5 mins and fill up their answer phone system and you get a call back after 2-3 hours) but when you explain your problem and the fact that the instructions are translated from chinesse so don't make sence . They can't help you as they don't have a tech dept and told me to first press one button repeatedly and if that Didn't do the trick to call out an engineer ( but they didn't know anyone in the kent area and told me to go on google) so I think the cus service is appalinng,in house knowledge is poor,the pumps are from China,they don't have tosiba com pressures as the last time I looked they came from Japan even with the telesales guy trying to convince me otherwise, and would i recommend them yes only to the tax man or an ex wife who took the house and the pool . Anyone know of a good heater foe a swimming pool

Perhaps try a quality heat pump instead of one of these heaps?

Hi, I bought and installed a Dream 12.5kw last year but cant make head nor tail of the settings in the handbook (nor can 2 local plumbers or a computer expert) so i have to go outside to turn it on and off! It works well in default mode and i am happy with it but would love to be able to programme it! Email me at xxxxx if you can help please!
