Solar thermal heat dumps – high tech or low tech?

Posted by: In Solar Thermal

Although not directly caused by the recent hot weather, we have been working on two very different solutions to overheating in solar thermal systems. The high tech device that looks like an air-conditioning unit is a fan cooled radiator fitted as part of an oversized domestic system designed to contribute to the space heating requirements […]

Blue sky thinking on Sports Hall roof

Posted by: In Photovoltaic

The recent hot weather has been ideal for completing the Schuco roof mounting hardware for our latest 50kW solar panel PV system on the Sports Hall roof of St George’s school in Harpenden. The standing seam metal roof  on this relatively new building has allowed our team to make short work of the 400 clamps […]

Biomass boilers in Buntingford

Posted by: In Biomass

Our recently commissioned ETA PE-K 45kW boiler sits snugly at the back of the garage and is now supplying heat and hot water to the house, some 40 metres away. Clearly there isn’t much demand for heat at the moment but it’s always an impressive sight to watch a boiler heat an 1,100 litre buffer […]

Jacket required, but no ties

Posted by: In Biomass

The 1100 litre buffer which accompanies this 45kW biomass boiler was delivered in its ‘bare’ state for obvious transport and installation reasons. At nearly two metres high and weighing the best part of 100kg, we were able to manoeuvre it into position in the corner of the garage using the inlet/outlet ports. Looking slightly shocked […]

Making the most of the available space

Posted by: In Photovoltaic

One of our recent clients wanted a large array but only had limited space available on the roof of his house. The south east facing roof had a velum window and the south west roof was cluttered with a dormer and adjacent soil stack, all of which limited the array to a disappointing 1.25kW. Switching […]

David and the District Heating Main

Posted by: In Biomass

In the course of one our latest biomass boiler installations, we had 40 metres of flow and return pipework to lay underground between the main house and the garage. We used a local digger hire company who’s skilled driver was able to tease his way through the pipework, wiring and drains we came across. He […]

Sunrise over Letchworth Garden City

Posted by: In Photovoltaic

As elegant as a pinstripe suit and a smart addition to any roof, these Sunrise Solartech 250W panels have found a sunny a roof in Letchworth. Having seen numerous conventional panels with blue silicone modules and silver aluminium frames, our client liked the look of the black frame, black tedlar backing and black silicone modules […]

Sunshine and showers in Stevenage

Posted by: In Photovoltaic

Weather forecasts are getting better all of the time and the ‘two drop’ icon featured heavily in the outlook for an installation in Stevenage earlier this week. But fortunately, the sunny spells were longer than the rainy periods and, despite the odd damp patch (we came down from the roof when there was thunder and […]

Separating pellets from dust – riddle me that!

Posted by: In Biomass

One of our clients had a problem with dust in their pellets and the auger was struggling to deliver the fuel correctly. Having determined why the dust was present we set about clearing the intermediate hopper, the transport auger and the collection box of the main store. Armed with a dustpan and a powerful vacuum […]

Servicing can be a dirty business

Posted by: In Solar Thermal

We recently completed a service on a solar thermal system installed by another company who, sadly for the client, is no longer in business. The pressure had dropped to nought, the pump was making an awful noise and the system had stopped producing hot water. It became clear the reason  there was nothing showing on […]

He said “Not only will people have warmer homes and cheaper fuel bills, they will reduce their carbon emissions and will also get cash payments for installing these new technologies”. Now that’s music to our ears. […]

New home for solar thermal next to BenQ PV

Posted by: In Solar Thermal

The large solar thermal collector on this house near Chesham had been in residence for many years. Formerly part of a swimming pool heating system elsewhere in the county, we decided it needed to move again to make room for a smart array of high performance BenQ 325W PV panels. But this time it only […]

The Energy Minister, Greg Barker, recently Tweeted an enthusiastic message to say the domestic RHI is imminent. The scheme has been talked about since 2009 and gone through many stages of consultation but has now been through both the Lords and the Commons and is signed into law. It’s great news for householders who can […]

Perfect Perlights in Hemel Hempstead

Posted by: In Photovoltaic

These nicely made Perlight 250W ‘all black’ panels produced a really nice looking installation. Matched to one of our favourite Eltek 3.8HE-t inverters, the system is performing well too and making the most of the spring sunshine.
