Which do you have now? Which is best for your property? Which will suit
your lifestyle? What improvements are cost-effective? What are the
Building Regulations requirements?
Controls
Electronic programmers, used with correctly designed systems, can offer independent timing of heating and hot water periods.
Programmable Room Thermostats allow you to set reduced temperatures at times of low occupancy, or high activity!
Thermostatic radiator valves allow guest rooms and 'best' rooms to be controlled at reduced temperatures when not in use, prevent other heat sources such as cookers and gas fires from causing overheating, and take advantage of solar gain.
Cylinder Thermostats, in conjunction with motorized valve(s), will eliminate unnecessary boiler firing (cycling),
Which of these measures will meet the regulations and help minimize your fuel bills?
Boiler Efficiency & Condensing Boilers
On behalf of the Government a boiler database showing the efficiency of gas and oil boilers sold in the UK has been developed. The SEDBUK (Seasonal Efficiency of Domestic Boilers in the UK) is the average annual in-use efficiency applicable to a particular boiler.
| Typical seasonal efficiencies are:- | Old Boiler (heavyweight) | 55% |
| Old Boiler (lightweight) | 65% | |
| New Boiler (non-condensing) | 75% | |
| New Boiler (condensing) | 88% |
A condensing boiler is a more efficient appliance which cools the flue gases to the extent that the water vapour produced during combustion* is condensed within the boiler (hence recovering the latent heat of evaporation) and must be run to drain.
* The combustion
of natural gas is represented by the equation:
CH4
+ 2O2
~> C02
+ 2H2O
Condensing boilers are available both gas-fired and oil-fired, and from spring 2005 (for gas) and 2007 (for oil) the Building Regulations will require that all new or replacement boilers are of this type except in a small number of special cases
Note that some water vapour remains in the flue gases, and condenses when it comes into contact with the colder outside air, and so this type of boiler produces a "plume" - a "cloud of steam" - from the flue terminal whilst in operation.
Which is the best boiler for you?
Boiler Sizing
A smaller boiler working hard will be more efficient than a larger boiler cycling (switching on and off) more often.
Ensure your boiler is correctly sized. not oversized!
So what does all this mean to the layman ?
Fitting the right boiler and the right system at the right price is a
complicated matter best left to the experts at Heating
