10 Top Tips for home heating energy savings

Speaking at the launch of National Heat Week, which will promote
home-heating efficiency from 4th to 12th February across 17 Stanley
Centres nationwide, independent heating and energy expert, Seamus
Brennan (B.Sc. Mech. Eng. Heating Consultant & BER
Assessor) said that stoves are up to three times more energy
efficient than open fires and keep the house warmer even when not
in operation due to the reduction in ventilation heat losses.
- Open fires are wasteful of energy with more than 70% of the
energy going up the chimney. Replacing an open fire with a stove
will improve the home BER energy rating on average by 8-10% per
annum, resulting in lower heating costs.
- 20ºC is an ideal room temperature. Turning down thermostats by
1ºC can reduce annual space heating energy consumption by 10% with
an equivalent reduction in greenhouse gas emissions. Heat bedroom
areas to less than 18ºC.
- Proper temperature and zone control of your central heating
system can reduce fuel consumption by 10-20%. There is a
Sustainable Energy Authority of Ireland (S.E.A.I.) grant for a
heating controls upgrade.
- Homeowners can typically reduce their energy usage by up to 20%
by installing a high efficiency condensing boiler or range cooker
as a replacement for older lower efficiency models. There is a
S.E.A.I. grant for this measure.
- Regular servicing of your heating boiler is recommended. For
example, servicing a kerosene boiler, which has not been serviced
for 3 years, will bring about an immediate fuel reduction of some
5%.
If a radiator is mounted below a window, a projecting window-board
or shelf above the radiator will direct warm air into the room,
reducing heat loss through the window.
- A lagging jacket on your hot water cylinder will keep water
hotter for longer and pay for itself in 2-3 months. If replacing
the hot water cylinder, a rapid heat recovery cylinder with
factory-applied insulation should be considered. Such insulation is
more effective at retaining heat than a lagging jacket, is less
easily damaged and cannot be pulled out of place.
- Heat the hot water cylinder by means of the central heating
boiler rather than by immersion on full rate electricity, as the
running costs will be much lower. Use a timer if the immersion
heater has to be used.
- Combining solar collectors with a wood-burning stove provides
an ideal year-round renewable energy heating solution. A solar
collector system can provide around 60% of your annual hot water
needs for free (80 to 90% in summer). There is a S.E.A.I. grant for
solar panels.
- Insulate your attic and save up to 20% on your home heating
bill. Much of the heat loss from a house occurs through the windows
particularly if they are single glazed. Keep curtains closed at
night and ensure that the curtains don't hang over the radiators.
