(1) The main stumbling block is the cost of installing the gigantic network of pipes needed to carry hot water from the central boiler to hundreds of homes.

(2) It had five indistinguishable letters where the ship's name should be, and the two-cylinder compound steam engine and single boiler correspond to the machinery fitted to the Clyde.

(3) A single burner, inside the boiler , supplies heat for one or more space heating zones and a domestic water heating zone.

(4) You can buy it in a kit, but you will need a plumber to help you connect the system to the boiler .

(5) Paul stationed himself in the bedroom window, and I was in the garden and the boiler had reached working pressure so I flipped the piston to start it.

(6) This meant that the boiler generated more power, so the Rocket was able to go faster than its rival, and thus secure its place in history.

(7) This sudden demand for water must have somewhat overloaded the boiler as the hot water ran out almost immediately.

(8) Once fired up, a boiler and radiator central heating system can heat an average room a great deal faster than an equivalent underfloor heating system.

(9) Steam turbines use steam raised in a boiler as the gas that turns the blades.

(10) This reflects the best a locomotive can do based on the quality and quantity of steam delivered from the boiler .

(11) But the principle of generating steam in a boiler under pressure and using it to push pistons back and forth in two or more double-acting cylinders, is just the same.

(12) As part of last year's work the boiler and central heating system was upgraded with the bedrooms and function suites undergoing redecoration.

(13) The steam was generated in a separate boiler and brought into the sphere along a hollow spindle.

(16) I rather thought sacrificing virgins to their gods had gone out with the clothes boiler , but sometimes I wasn't too sure.

(17) No separate storage tank is needed in the tankless coil water heater because water is heated directly inside the boiler in a hot water heating system.

(18) In contrast, steam turbines use steam generated in an external boiler to rotate the fans.

(19) Have your boiler and central-heating system checked over once a year by a qualified engineer.

(20) Wood combination heaters can be either hot-air furnaces or hot-water boilers .
