i have avoided the multiple threads on boards about solar because to be honest its becoming like religion there is just to many arguements for and against.

From the bit of research about efficiencys i have done, from selling them and from following there progress i have come to the conclusion it is not work investing in solar unless

1. You pressurise your entire house in which case you will also need a pressurised cylinder.

2. You introduce them at the stage of building


Either way i have come to the conclusion that the cost v's payback is not worth it.


Have to diss-agree on this one I'm afraid. I agree on Heinbloed's point.

Hi guys solar should provide 90 % your hot water from march-oct and 40% from oct to march....The average home will only use our heating or showers for hot water from march to oct,as we have heating off.Then we have our heating on from oct march anyway so it's less costly to bring up our bottom line temperature. your average electric shower costs 125€ to 150€ per adult head per annum. Women use 40% more water than men. Your ratio of heating water to space is bout 3 /1 hot water costing way more....

You should work out 50 litres of water per person in your house minimum size tank should be 200 litres.Every house in Ireland with small 90 litre copper tanks under heating water. I future proofed my own I put in 300 as I built it in case I have 3 -4 children. I only use 800 euro kerosene house 4380 sq.ft. I turn off heating early march til roughly 3rd week oct.

...also installing solar panel, my problem is controlling the heat output to my rads, its a nightmare turning on/off switches, motorised values and pumps etc...

Controlling the heat output from the rads is done via the radiator thermostat at the radiator.
There are mixing valves (available from the plumbing center) which can be installed between flow and return in a CH system as well, controlling the temperature of the water going to the radiators.

The CH system's components should be installed as an integrated system, parts should match. Undersizing and oversizing should be avoided.

The energy consumed putting up wind farms and Manufacturing solar panels is always forgotten when people discuss green energy


You've all been brainwashed people ha ha
