Solar thermal

[jason121]

Need some advice regarding a solar thermal system. To remove existing cylinder is going to be a nightmare, small cupboard and pipes covering the cupboard. So I am thinking of installing separate cylinder and piping the hot water from the solar cylinder into the bottom of the existing cylinder. Any thoughts.

nope....

Thanks

Sorry Jason, I know the answer above did not help, it did make me smile though.

I can not help you at all on this one though, but I am sure someone will.

Is this a customer with or without existing PV ??

 

[jason121]

No PV, Oil boiler, not a lot of space on roof for 16 panels

 

[sedgy34]

Even at 8 panels they will get more benefit than thermal
anyway if you have your,mcs solar thermal,unvented hot water, and oil registrations you can do what your looking to do.

 

[jason121]

Can you explain your statement Sedgy

 

[sedgy34]

Can you explain your statement Sedgy

Which part

 

[jason121]

The PV part about the 8 panels

 

[sedgy34]

If you can get 8 Pv panels on the roof surely they will benefit better than solar thermal

 

[jason121]

Heating costs is more than his electric consumption and more expensive being oil

 

[sedgy34]

Get him to have biomass

 

[jason121]

I am thinking of installing heat pump cylinder with solar thermal. That way he will be ready for heat pump system later on. What's your views on the pellet prices in the next few years, will they be expensive ?

 

[sedgy34]

With the pellets there isn't any import as this country can deliver stock so no don't think so, heat pump is the way forward

 

[Earthstore]

What is wrong with a PV system and an export divert unit? (read the many threads to choose) Surely the sums would work out better.

Going back to op I think there can be problems with the legionla disinfection as the first cylinder fed via solar could be sat at ideal temp, make lots of infested water and could run right through second cylinder. Chage cylinder for thermal store over comes lots of issues! Gledhill do some good ones. No discharge pipe work, not a rocket waiting to go through the roof and no need to protect against legionla as its and instantaneous water heater? Hope this helps. Aj

Biomass, you're still in the hands of a 3rd party fuel provider, at the levels the Governements wants to promote Biomass we'll be a net importer of Biomass fuel. - Who control's the price of fuel and the costs of your heating then ???

vented or unvented?

could be worth considering a solartwin system if it's vented, now being made and sold by discrete heat in Manchester at reasonable trade prices, and would mean no need to replace the tank, just plumb in to the cold and hot water pipes from the tank or even near the header in the loft.

Have a look at things like the Willis Solarsyphon or a solaPlug. I haven't fitted either of these but have had extended chats with both companies at exhibitions. They may provide a cost effective solution for you if the existing tank is large enough.
