Bore holes usually work because they are taking the heat from the Earth rather than the heat from the Sun, geothermal. If you're using trenches IE 1m to 3m deep this is more heat from the Sun. Agile quotes rubbish, a cold snap will never freeze 10m down!!! Get real! Cold mains water pipes to...

Havwe stripped off tiles in shower room as the waterwas penetrating and causing a real mess. The wall about 1m up from floor level are sodden. The walls just have bonding on them, no finishing plaster. Is this going to be a problem when re-tiling or would the walls need to be finished...

Ariston service engineer came over yesterday and changed the PCB. Works fine now. Engineer said, it's very common, third PCB he'd changed that day with A01 fault.

oilman - Let me explain what the article you keep referring to means. I have read it and I understand it, unfortunately you don't. Moron. The guy in the article has installed a Navitron vacuum tube system for his hot water but also a small PV system for his electricity. There are two...

OilMan - You really are a buffoon. "Elliott resorted to a stab in the dark" You're the one in the dark. You don't know what your talking about when it comes to renewables, and it's been obvious. Why argue about it when your using PV gain from a small module to justify why solar thermal...

You haven't mentioned electric, I was taking a stab in the dark. With the amount of mis-information you've written so far I would of thought an electric powered heat pump with a cop of 1/3 would be your answer to the looming energy shortages. Thanks for all your comments OilMan it's been...

Thanks Frank. Not good is it really, brand new boiler already on the blink. Do you know if it's a common complaint?

Oil Man - Solar Heating/Power is the future be it thermal, heat pumps, biomass or what ever form it may come in. Please don't tell me that your secret form of electric "solar" heating is a heat pump.

Well said Doctor D. Some sense at last!

The issue is to reduce our impact as a race, saving money is a secondary issue.

Resol is a German Brand.

Yeh, the whole issue has become "jobs for the boys" as far as the government is concerned. The Earths climate does cycle and has been so for billions of years. But as a race we should be reducing the impact we have on the planet, without question, regardless of how much money we'll save. The...

He's talking about PV, this thread is about solar thermal. The guy who measured it, in case I'm loosing you here. 300W thermal energy on an average day??????????????? You are talking rubbish. If your talking heat energy a panel puts out 700W per m2 per hour on a good day. Your using...

Brickit - Don't go for intergated boiler and solar controls because the boiler will override the solar system if there is an overcast period during the day. The best way to use the solar thermal system is to have the boiler and solar running of seperate controllers. It's standard practice to...

The amount of embodied energy would be would be paid back in a few years where solar panels are concerned. Never paying back? What a joke! The sad state of affairs is that a pluming and heating engineer such as yourself doen't know hat he's talking about, my laptop uses 19V and about 5A...

Tapping the Sun: A Solar Water Heating Guide by Chris Laughton. £7.59 Buy this from Amazon, it's a good guide.

It's a shame people think like you. It's why the worlds so polluted and climate change is an issue that's going to make our planet a hard place to inhabit for our children. Solar should be on all new builds and everyone should have it on their homes and offices. Your attitude is narrow...

One of the best drainback systems is the Zen Eager system. It been around for years and isn't available "off the shelf" in you local Plumb Base. Don't go for the Viessmann tubes, your going to be dealing with high temperatures that will casue you problems unless you know waht you're doing...
