if in doubt bang in a heat pump! I like your style craig!!!

DO you wanna come fit another unit for me in my spare back bedroom?

Any chance of a sticky for heat pumps? It seems people KEEP coming to the forum and not knowing about them?

Agreed we have to keep repeating ourselves.

I think I'm going to get one as we are planning on installing another unit now in our garage, this will mean we are 100% on heat pumps

Craig,

Any chacne of a couple of pics of the outside walls of your house and maybe a couple of rooms you have the units fitted to?
It sounds like you've got a fair covering on your external walls now.
Was it the case that you did or did not need planning permission to do this?

Can you use these units for turning a room into a cold store efficently (walk in larder/fridge), and the heat generated from that to heat the rooms in the house?

Housesitter:

Here is a video of the outdoor unit, it is actually operating but in a defrost cycle at this point, you can see that traffic noise can be heard over the unit.

No planning permission was needed.

THe pipes you can see are now boxed in in plastic trunking which match the colour of the brick work, comes in various colours etc.

My unit is a large unit as it is a multisplit system which can have upto 4 indoor units connected to it... currently I have two.

Hello Richard,

Excuse me for butting in here. I have just looked at your video and notice that you are in Leeds. I was wondering if I might come over and have a look at this system ?? Maybe you could also run me through all the ins and outs of this type of heating / cooling. Could this sort of system be used in a 'mobile' application ??
I have a 40' double deck trailer thats been converted into a motorhome and I was wondering if this sort of thing could be used in that. The beauty of these sort of systems seems to be the low (Ish) power consumption and the efficiency / output ratio.
This looks a really interesting way to heat / cool something like my trailer. Hope to hear from you soon. I am near Wakefield btw....

Im sure something can be sorted out for you visiting i can explain the system etc. I work in this line of business too so I know what im on about.

If your motorhome is one that doesnt travel about then you could use it for that otherwise you have to think where are you going to put the pipes. The outdoor unit is bolted right down and the piping is solid so its not as though I can just disconnect it and remove it, i would have to call the installers back out to disconnect and pump it down for me. Then reinstall in new home/location.

I'm sure you could mount the outside unit somewhere on the exterior of the motor home, needs to be a good solid fix as movement could fracture connecting pipes (perhaps using the flexible pipes would be an advantage). The main problem may be the electricity to run these mains powered units. If you're going to be hooked up to the mains then obviously that would work.

This is effectively what all these refrigerated lorries driving around use its just you'd be heating internally some of the time. It works for them so I'm sure its do-able.

The fridge lorries run heat pumps without a mains connection (although most have a mains hook up option for when parked) so there may be some units out there that are truly 'mobile' using the engine when off mains and mains hook up when its available.

If your options to space heat are bottled gas, oil or electric then a heat pump is probably the most effective in both cost and function. Just make sure the trailer is well insulated!

I dont think you would be allowed to be driving around on the roads with a huge condenser unit (outdoor unit) on the back or top of the trailer (you also mention its double decked so cant go on top) but if it fell off the back because these units are heavy. Mine took 2 men to lift.

However there are prob options available for mobile homes that use the same technology.

Ive put a post on another forum re mobile home air con and will see if anyone comes back with suggestions.

A significant number of the vehicles I see driving around on a daily basis have huge condensers mounted on them,usually high up on the front above the cab. If they weren't allowed our food supply chain would collapse.

Its got to done right of course, to ensure safety, and I'd be surprised if there aren't purpose built units for these sort of applications.
