more than 3 years

and you have a cut off on the size or property that it will work in. Also how much land have you got ( size of Garden ) and do you want it Dug up

I would only suggest fitting GSHP's in brand new properties

( they are also useless with radiators underfloor heating only TBH )

Underfloor heating is far superior to radiators though (I wonder can you use underfloor heating with a standard central heating system?), and it provides cooling in the summer. A geothermal system would complement a standard central heating system normally. You can also get grants of around £1,500 towards the cost.

As much as I rate underfloor heating, I could only really see it being installed in the bathroom as it needs totally gutting.

Most of downstairs floor is natural stone and there's no chance that's shifting.

at max 12KW from a GSHP ( or geothermal pump ) It would not work with radiators very well and would probably then constantly call from the backup Electric heating element

plus anyone thinking of putting one in your terraced house with a small garden reading this get a quote for a borehole aswell thats an eyeopener

Stick with a Unvented cylinder + rads mate and a nice system boiler and put a fancy towel rail in there
 
I agree with an unvented cylinder, it's not much harder to install so don't let anyone fob you off with that. Most unvented cylinders come with labels/instructions saying where each pipe should go so it's not difficult. Just make sure that the person is qualified to do it, it needs a special certification (I've done it myself, that's how I know).

Mains pressure hot water for the win ;) .

I'm liking the sound of that mate. Take it this your line of work then? ( he says noting your location is only a short drive along the A59 to me)
 
2 weeks ago i got my old back boiler removed, all the rads removed and a sealed combi bioler system put in with all new rads plus fitting a towel rad in bathroom and an upright rad in the lounge all for £2800 i was all done in 1 day, only differance i have is that most of the piping was already there. Oh i have a 3 large 3 bedroom house and all in all 7 rads were fitted.
 
You can install an Unvented Cylinder yourself as long as you inform the local concil

I changed my Boiler in the house added a couple of rads and replumbed the lot in about 2 days

Total price for Boiler and Rads and fittings = 0 muhaaa ( It helps if your in the know ;) )

Are you sure you're not thinking of a thermal store? Works in a similar way, but is not the same as an unvented cylinder (though people often mix them up). I'm pretty sure unvented cylinders MUST be installed by a certified person. They are perfectly safe is installed properly but if something goes wrong then it's not too good. Temperature is the problem though, not pressure (not directly anyway) usually caused by an untrained person installing a normal immersion heater with no emergency cut off.

Edit: http://www.trainingbyreactfast.co.uk/pdf/BR_PDF_ADG_1992.pdf <-- Builging Regulations on unvented hot water there for you. Says it must be installed by a certified installer.

The G3 regulations have been devised as the method to ensure that products which store in excess of 15 litres of hot water are equipped with safety devices capable of preventing the water from exceeding 100°C.

In the past it has been permitted for the installer to fit the various safety devices at the point of installation and have the installation checked by building control. This has now been restricted to exclude the temperature and pressure relief valve which must be factory fitted.

It is no longer possible to comply with the regulations using a kit of parts and a Building Control inspection.

Unvented storage products over 15 litres must include the factory fitted temperature and pressure relief valve to be legally installed.

Thats why all the cylinders on the market over 15LT come with the safety features pre-installed so as anyone ( Competent person ) can fit it then building control can certify the instalation


And yes I know the difference between a Thermal Store and an Unvented Cylinder


This is what happens if those safety features are not checked and not working

> Enjoy

( I havent got sound ATM but I think that was a 150-200 LT cylinder )
