Heat pump considerations.
The working ranges for the different type of compressors.
The source and delivery. The typical stand alone AC units is air to air and that is efficient in climates where outside temperatures seldom goes down to 0 degree Celsius. In colder climates, a system earth to water is by far the best efficiency. That means that the collection circuit is water pipes in earth and under freezing level. This guarantee constant temperatures between 5 to 12 degrees, depending on geographic location. The maximum working conditions can be achieved.
On the delivery side, radiation is also much more efficient delivery than heating air, but the highest delivery temperature are 45 degree Celsius or slightly lower. The low delivery temperatures make it ideal for heated floors. If used in radiators, they have to be larger sizes than what is practice, because of the low delivery temperatures.
Preferable are DC compressors who permits capacity regulation with variable speed. This give clear efficiency advantages, compared with an AC compressor regulated with start/stop, 20 to 30% less energy use with variable speed is not uncommon. It also make the parameters for the room climate easier to manage.
Energy saving and cost considerations.
It is considerable savings of energy and costs, when using heat pumps. To give you a picture, we will use cost savings as units and descriptions.
The following comparisons, use blower heat fans as starting point and considers each change on its on,
Change to oil filled electric panel radiators from blowers, 10 to 15% savings.
Central pulsating thermostat, with clock and ventilation protection, around 10% to 15% savings.
Change to water filled radiators with central heating and central thermostat, 25 to 35% savings.
Using central high efficiency heating with oil instead of electricity give 40 to 50% savings.
Using heat pump with air collector in warmer climates and earth collector in colder, 50 to 65% savings.
Producing hot water with oil instead of electricity, around 40% savings.
Production of hot water with heat pump recover from ventilated air. 65% savings.
Production of hot water with solar panels (80%) and heat pump, around 90% savings.
Above savings is not accumulated effects, but the difference between one installation to another can be up to 80% in costs and energy consumption. This comparisons are between worst and best case. Worst case being a badly insulated house with resistor heating of air in ventilation system and water production, best case a well insulated house with heated floors, heat pump and solar/heat pump recovery for hot water production.
The worst case situation is very common and very difficult to fit in with a total use of renewable energy sources. For the best case, it is very feasible to use solar (thermal and PV), wind and biofuel systems for the necessary energy production
