Elegance and style are mostly the factors why timber flooring is well-liked to home builders. Aside from that, timber flooring is one of the most gorgeous and long-lasting flooring options that any homeowner could make. It's going to add val This year when you go up into the attic to get the Christmas decorations take a look around the attic to see if there is any frost on the roof ceiling or rafters. If there is then you have a moisture problem that should be taken care of. Moi
Because of the increased risk of corrosion that arisesfrom water and air coming into contact with steel surfaces, a radiator circuitshould be drained only when absolutely essential. When this has to be done - toadd additional radiators, perhaps - you should tie up the ball-valve servingthe feed-and-expansion tank and drain from both the drain-valve beside theboiler and from any drain-valves provided at low points of the system. Youmust, of course, let out or switch off the boiler before attempting this. When refilling the primary circuit (or when refillinga direct system with boiler) it may help to prevent the formation of air - locksif you connect one end of your garden hose to the boiler drain-valve and theother end to the cold tap over the kitchen sink. Open them both up and thesystem will fill upwards, with air being driven out in front of the risingwater. As the central heating circuit refills, open up allthe radiator vents - and any other air vents that there may be in the system -and leave them open until water begins to flow through them. It is a good idea,when refilling a central heating system, to introduce a reliablecorrosion-proofer into the feed- and expansion tank to prevent future internalcorrosion, but you can do this only if you fill the system from the top, notfrom the bottom. Winterprecautions One final point: if you are leaving your home emptyduring the winter months, you should drain the main cold water storage cisternand, if you have a direct hot water system and will be away for more than twoor three days, you should drain the hot cylinder, the boiler and itscirculation pipes as well. Human memory is fallible. Leave a conspicuous noticeon the boiler and by the immersion heater switch saying: SYSTEM DRAINED - DO NOT LIGHT BOILER OR SWITCH ONHEATER UNTIL IT HAS BEEN REFILLED. Because of the risk of corrosion already referred to,the primary circuit and any central heating system connected to it should notbe drained in these circumstances. If you have a central heating system that iscapable of automatic control, leave it switched on under the control of afrost-stat, This is a thermostatic control, usually positioned in a garage orin the roof space, that will bring the heating into operation when apredetermined, near-freezing-point temperature, is reached.
