Does anyone who has the water regs qualification. Know if you resit it now it last for life or every 5 years? I did mine with my NVQ level 3 in plumbing and it says it only lasts 5 years. Thanks

Hi has anyone done the level 3 heat pump installation course? Is it worth doing? Thank you

Sorry just read the article the high bill was with an electrical heating system

And that cost is with a air source heat pump that will run at a cop of 3. So an electric combi with a cop of 1 would be alot more expensive?

I'm not designing a system. I just heard at work they were taking gas boilers out of a block of flats and replacing with electric combination boilers. I thought it sounded like madness. Just wanted other peoples fews. I thought airsource would be a better option. They could even put large ones...

Thanks wall could be better if individual units? Is it better to keep the flow and return to a minimum length. To limit heat loss before reaching the cylinder/ space heating?

Were could/would the heat pumps be sited if a block of flats no balconies.

It's for flats that are going off gas. Is there any other viable options for this?

So be alot more expensive to run, hear people complaining about heat pumps with a COP of 3 or more.

I have heard these are very expansion to run. Do they produce a COP of 1? Every 1kw of energy to 1kw of heat?

Easy to pick up I imagine?

Yeah id prefer to solder. But I think it's company policy

I am good at working with copper bending and soldering. However I have never used press fit before on copper. Is it easy enough to get used to/get fast at?

If draining the heating system on an Splan system with a indirect cylinder. If leaving the heating drained over night. Is it ok to turn the immersion on to the cylinder? It won't effect the coil if it's empty of water. Thanks

The telescopic version is cheaper. So would suggest the rigid one is better?

They have both been there now about 12 years so can't be bad where they are

I have friends that have worked there

I've had the pressure rise before due to the system creating hydrogen gas. Had to hot flush with a cleaner to stop the problem

Never noticed

Have you worked there I guess?
