I thought he was going to talk me through his eco-friendly boiler system.

It's eco-friendly, too, with a sophisticated boiler system and enhanced insulation that means the four-bedroom property costs as little as 500 a year to run.

Would an electric boiler system make sense, and could it be incorporated into the present system?

At this time, the boiler system was moved from the basement of the high school to the area between the main building and the annex.

The boiler system was entirely replaced with six small-tube boilers and new turbines, the latter partially from the canceled battleship.

Fifteen years later another and larger cheque winged its way through the post as his contribution towards the cost of her new coal-fired boiler.

The result was an odd, six-wheeled contraption which relied upon gasoline for locomotion and a coal-fired boiler for pumping water through hoses.

This vehicle had three wheels, the single wheel at the front, and a rear-mounted coal-fired boiler and two-cylinder engine.

Power for lifting and rotating was supplied by a coal-fired boiler supplying three steam generators (two 220 kilowatt generators and a 44 kilowatt auxiliary).

The traditional method of coal-firing the stills by hand was changed to internal heating by steam generated from a coal-fired boiler.

Fuel bills are up 'hugely' despite the installation of a more efficient boiler at a cost of 3,000.

The cashback can be claimed back for installing measures from insulation and draft proofing to a more efficient boiler.

Yes, this means a bill of at least 1,800, but an efficient boiler will reduce your heating bills in the long term.

Other measures include free loft lagging, doubleglazing and efficient boilers.

Over the coming decade, cost-effective measures will continue, including more loft and cavity wall insulation, more efficient boilers and power stations switching from coal to gas.

A few weeks ago, our central heating boiler leaked water over our laminate wooden flooring, ruining it.

My washing machine broke and the central heating boiler stopped working.

In the servants' wing, where the wall panelling at last gives out, there's a kitchen with 20-year-old cabinets, a warren of pantries and the new central heating boiler.

The most spectacular he'd ever seen was draped like a sheet down a central heating boiler - horizontal waves of papier-mâché, exquisitely layered and flowing like an abstract painting.

Early diesels were also fitted with communicating doors in the nose which allowed the secondman to access the train heating boiler of the rearmost locomotive.

Replace your oil boiler with one and you will be swapping an oil bill for higher electricity bills.

Every time a gas/oil boiler stops, it has to be purged with cold air to remove any combustible gases that may have accumulated in the boiler before restarting.

In between the boilers were converted into furnace oil boilers and again back to coal boilers.
