Heating
FACT: Heating and Hot Water can typically account for up to 60%
of a business’s energy use (Carbon Trust figures).
30% of this cost can be saved through good heating management.
FACT: Lowering room temperatures by 1oC, can reduce your
annual heating bill by 8-10%.
FACT: There are currently around three and a half million homes in
England with the very least efficient type of boiler (G-rated or
worse) - this means they are less than 70% efficient.
TOP TIPS FOR ENERGY EFFICIENT HEATING
Check the efficiency of your boiler. Boilers have an A to
G rating, just like many other electrical appliances,
upgrading an inefficient boiler could reduce your energy
consumption by as much as 25%. You can find out your
boilers efficiency rating from the user manual or from
www.boiler.co.uk
If you have radiators fit Thermostatic Radiator Valves
(TRV’s). These will enable you to turn heating down in
rooms that aren’t being used and automatically control
heating to desired levels. For bigger buildings consider
zoned heating systems with different time and
temperature settings as appropriate.
Lag all accessible pipes, pay particular attention to pipes
in plant rooms and boiler rooms, pipe lagging will
usually have a payback period of around 12 months.
Make sure that valves and flanges are lagged as well as
the pipe work.
Work to raise staff awareness of heat loss from opening
windows and doors, encourage staff to turn heating
down before opening windows and draw blinds at night
to retain heat.
If you have air conditioning, check that the air
conditioning thermostats are set above those of the
heating thermostats ( a minimum of 4˚ centigrade).
Otherwise the 2 systems will be working against each
other.
If you use small amounts of hot water in areas that
are a long distance from the hot water storage tank
consider installing electric point of use hot water
heaters. This will save the drawing of a large amount
of water in the pipes before the hot water starts
coming out the tap.
Where possible install additional insulation to
maximise heat retention. Insulate lofts and walls,
and carry out basic draught proofing. When
insulating always seek advice on air movement and
building breathability to avoid creating damp spots
and condensation.
Fit simple reflective panels behind any radiators
situated on external walls. When installing any new
radiators, try where possible to site them on internal
walls. They are a cost effective way of saving around
5-15% of your heating bills.
When carrying out upgrades and boiler replacements
consider low carbon alternatives. Investigate systems
such as solar thermal, ground and air source heat
pumps, biomass boilers etc. If installing hot water
storage systems, future proof the system by
considering additions of renewable technology. A
good plumber should be able to advise on this.
