When looking for a
source of heat for an energy-efficient home, it is worth paying attention to on the profitability of its purchase.
It's easy to calculate
that in the case of an energy-efficient house with a small heat demand, the
money invested in the expensive heating system will pay for itself for a long
time. Savings on heating bills do
not compensate for a larger expense for the purchase of an energy-saving
heating system as soon as at home, for which heating requires a lot of heat.
Will the investment pay
off?
It is worth to make a
simple bill to check whether by spending on a cheaper in use heating system
more, for example, 20 thousand. PLN
less than for a simpler one (more expensive in operation), it is possible to
obtain the cost of heating a lower house, though by 2 thousand. PLN annually. If not, then you have to wonder
whether this much more expensive purchase definitely makes sense? It may turn out that the tens of
thousands of zlotys saved at the time of purchase of a heat source are
successfully enough to cover higher heating costs over the entire service life
of this device (the lifetime of gas boilers is estimated at 10 years, heat
pumps at 15-20).
Cheaper is not always
worse
In a very well
insulated, energy-saving house, it is not uncommon to use electric heating for
electricity, although the costs of generating heat from electricity are very
high. Because if the heat needs
relatively little, then in the general balance of expenditure, the smaller part
is also for exploitation, and larger for the investment - therefore it is best
if it is the cheapest.
