When do I need an air-water heat pump without a tank? If you already have a water tank that you want to keep or if you need a size of the water tank that is not available among the integrated water tanks, then it is a good idea to look at a system without a water tank. This gives you greater flexibility in your choices. It is also suitable in colder climates as it is refrigerant that runs between the indoor and outdoor unit instead of water, as in a monoblock. Therefore, there is no risk of freezing, and the main components are protected in the indoor unit. Many with tight spaces for an indoor unit choose one without a water tank because the indoor unit is much smaller, and they can find a suitable tank that fits the tight space.
Is an air-water heat pump without a tank a cost-effective solution? Yes, since you usually use an existing water tank, the investment is not as costly compared to when you buy with an integrated water tank. The system offers higher flexibility, and therefore you have a greater opportunity to influence the total cost.
What is an air-to-water heat pump? An air-to-water heat pump is a system that extracts heat from the outside air and transfers it to a refrigerant (split system) or water (mono system). This heated water is then used for space heating through radiators or underfloor heating systems and can also provide hot water for domestic use.
Is an air-to-water heat pump worth it? Yes, an air-to-water heat pump can be worth the investment, especially in climates where heating is needed for a significant part of the year. These systems are energy-efficient, environmentally friendly, and can significantly reduce heating costs over time compared to gas and oil. If you already have an water-based heating system it is fairly easy to switch to a heat pump.
Do heat pumps work in cold climates? Absolutely, heat pumps are very popular in the Nordic countries. We have seen heat pumps in Sweden for a long time now, and it works good.
What are the disadvantages of an air source heat pump? Disadvantages include some reduced efficiency in very cold temperatures, the need for a backup heat source in extreme climates, initial installation costs, and potential noise from the outdoor unit.
What is the most efficient air-to-water heat pump? The most efficient air-to-water heat pump often depends on specific needs and climates. Brands like Panasonic and Mitsubishi Electric are known for producing highly efficient models. Look for high SCOP (Seasonal Coefficient of Performance) ratings for the best efficiency. 5 in SCOP-value means that the heat pump will provide 5 kW of heating out of 1 kW of electricity. Compared to an electric boiler that will provide 1 kW heat out of 1 kW of electricty.
Can air-to-water heat pumps cool? Typically, air-to-water heat pumps are designed primarily for heating. However, some models do offer cooling functions, often referred to as reversible heat pumps.
Are air-to-water heat pumps noisy? Modern air-to-water heat pumps are designed to operate quietly, with noise levels often comparable to a refrigerator. The level of noise can vary between models and manufacturers.
Where is the best place to put an air-to-water heat pump? The best place for an air-to-water heat pump’s outdoor unit is in a space with good air circulation, away from direct sun exposure, and preferably with a shorter distance from the indoor unit to avoid to much pipe work. It should also be placed away from sleeping areas to minimize noise disturbance.
Why are air source heat pumps so expensive? The expense comes from the technology used in air source heat pumps, the cost of professional installation, and the materials needed to set up the system. However, their energy efficiency and lower operating costs can offset the initial investment over time. You do not need yearly service contracts for a heat pump.
