Solar panels have never been so attractive

Solar panels have never been so attractive

With the feed-in tariff due to start in April 2010 (after a short consultation period to October) the benefits of installing a solar photovoltaic (PV) system on our houses before the end of the 2009 are probably better than we will ever have again. Simply put, if you have a PV installation befor…

Will feed in tariffs change the market?

The announcement by the Government last month of proposed feed-in tariffs (FiTs) for renewables from next April marks a fundamental change in the way small scale renewables are incentivised in the UK, and is long overdue. There is no question that feed-in tariffs are the right mechanism to use. …

What is the best solar hot water panel for a small space?

Question from YouGen user: I have a 7 year old Solartwin panel on my roof which I believe is performing poorly and is not metered. The company say that the harder water is likely to be too much for the panel and that it needs an indirect panel. Thus I feel I need to replace it. It is a landscape sha…

Dealing with silt in your rainwater harvesting system

Over time, silt will build up at the bottom of a rainwater tank. Imagine you have a bucket of mud and water. If you leave it, the mud will settle at the bottom leaving clear water at the top. If you then empty another bucket of water straight in, the pressure of this water stirs up the mud, making t…

Is your wood fuel up to standard?

A log's a log isn't it? Well, not if you want it to burn well it isn't. As with all woodfuel, the efficiency with which it burns depends greatly on its moisture content. For logs to burn efficiently in a boiler the moisture should be at or below 25%. That’s not all. They should …

Lag your pipes

I've just been asked whether it's worth lagging hot water pipes. The questioner said: "We have quite long hot-water pipe runs in our home. We've fitted the system boiler and thermal store nearer the bathroom, but we still have to run a lot of cold water to get hot water in the kitchen 2 floors …

Do you want warmer homes at an affordable price?

Fuel poverty is in the news again with oil prices on the up. The traditional way of dealing with this has been to give people in need a bit of cash to help them over the winter.

Is wood fuel sustainable?

Is wood fuel sustainable?

Biomass sounds like a great idea, but I've always had a bit of a nagging question at the back of my head about whether it would be possible or sustainable if we all suddenly converted to wood fuelled heating. Haven't we, over the years, been denuding Britain of trees to such an extent tha…
