热泵是否值得？

Hello, One must seriously consider before buying a heat pump - whether a photovoltaic installation will be added to it? If not, the purchase will not pay off for a period of 7-10 years. Heat pumps cost from 20,000 to 50,000 zł, so it is not an expense that would go unnoticed in a household budget. If a photovoltaic installation (another 40,000) cannot be installed, or the amount of energy obtained is very low, one could consider an accumulator stove - a modern version of the so-called Kaflak. The cost is much lower (10,000-30,000 zł), and they accumulate up to 60% of heat, depending on the needs and insulation of the premises. The size of the space also matters - accumulator stoves are suitable for an area of up to 100m2. Above this size, such a stove would need to be supported by an additional heat source. As for me, I bought an electric stove (expense of around 5,000 zł, so cheap). In addition to that, I will add photovoltaics with an energy storage. After insulating the building (currently not insulated, unless counting the cement mortar on the bricks) and installing the energy storage, it will be a cheap solution for me because I have a place to install photovoltaics with a capacity of about 10kWp and an energy storage (I do not know yet which one, but it cannot be more expensive than 20,000 zł). I would prefer to spend the amount for the heat pump (good quality, around 30,000 zł) on a photovoltaic installation. The electric stove (Polish product - Elterm stove) heats an area of 117m2, with an uninsulated ceiling and roof above this area. With the power set at 8kW and 66% efficiency of the heating elements (I can adjust it every 2kW or 4kW: 2, 4, 8, 12, 18, and every 33% usage), I have 20-22 degrees in the house (depending on the time), and the electricity bill for January was quite high - 3,000 zł. It was 1,600 zł for December, but it was quite warm. That is a lot, but around 300 zł of it is just the regular electricity consumption. In January, there were temperatures below -15 degrees, and it was still 20-22 degrees in the house. The stove also heats the water tank, of course. Was it cost effective? Gas would maybe be cheaper, but there is no gas pipeline in the village. The municipality offered the option to buy coal/pea coal for 2,000 zł/ton, so it would be around 2 tons in January and 1 ton in December. In a 100m2 insulated building, with such cold temperatures, 1.5 tons of eco pea coal with 28kJ was used. There is no insulation here. Was it cost effective? It will only be known after installing the energy storage. For now, the only option was the electric stove and the 12w tariff, programming the stove to heat to 22 degrees at night 22-24, water and house from 4-6, and then water and house from 13-15 during the day, and the house from 18-19. Outside of these hours, it maintains 20 degrees in the house. With just the energy storage, the price would be 300 zł lower. To sum up, several factors must be taken into account: area, the possibility of adding panels and their capacity, energy storage, electricity tariff, and the budget for the entire installation. It is also worth considering when and how many degrees are required in the house - constant comfort or warmth after work. The energy storage can be purchased earlier, charging the electricity at the cheaper tariff to support the heat source. As for me, I ran out of money for the rest - buying a house on credit + materials for the roof (to be replaced in the spring), pipes and radiators, and occasionally bought tiles and paints, and replacing the entire electrical installation. All of this ate up so much of the budget that photovoltaics will have to wait until 2025. If not, another loan will have to be taken, but then there will be no money for further investments. Hence, the most important question to start with is what budget can be allocated.

A colleague from work has a ground heat pump. He doesn't have solar panels. On average, his monthly bills for the year 2023 were around 500-550 PLN, considering that he uses electricity for everything and the heat pump itself consumes about 7MWh of energy. The house is a two-story building, well insulated with 15 cm of graphite polystyrene. The advantage is undoubtedly the convenience of use, while the disadvantages are the installation cost and dependence on electricity. I am not talking about periodic power outages, but rather about legal and economic conditions. In my opinion, the installation makes sense for people who have solar panels in a system with discounts (agreements until March 2022) and using current subsidies. My neighbor installed panels with an air pump last year, and when the temperature dropped below zero outside, he switched to heating with gas. I also considered installing a heat pump for a moment (I have solar panels and an agreement from 2021), but I gave up on this idea - based on my calculations, it is not cost-effective. I am upgrading the boiler room based on a heat buffer with potential additional heating using electric heaters at the night tariff. I have my own forest and storage space, so I will install a gasifying boiler, which will be much more economical in this setup compared to the current one. Of course, EU policy may turn out to be crucial here, but for now, I am not "going for the pump".

Hello! I have a heat pump in my house and I definitely recommend its installation. The heat pump is an environmentally friendly and energy-efficient heating system. It uses energy from renewable sources such as air, water, or soil to produce heat. It is a very cost-effective solution because the heat pump consumes much less electricity than traditional heating systems, such as gas or oil boilers. Additionally, the heat pump does not emit carbon dioxide, which makes it more environmentally friendly. It is also worth noting that the heat pump can be used for cooling the house in the summer, which provides an additional benefit compared to other solutions. However, it should be remembered that the installation of a heat pump involves some initial costs. However, in the long run, significant savings can be made on energy costs. In conclusion, if you care about an environmentally friendly and cost-effective heating system, it is worth considering a heat pump. I recommend it!

My friends have it and they highly recommend it! The installation is super easy, and then the device is actually almost maintenance-free. The biggest advantage is the low costs, of course, once you invest the money at the beginning. The lifespan is also around 30 years, so it pays off when you do the calculations. Another advantage is that it has the size of a larger fridge, so it doesn't take up much space. And if someone cares about the environment, it also has many advantages - it is one of the most environmentally friendly heating devices.

There are so many factors that there is no one simple answer to such a question. It will work in one house and conditions and not in others... FIRST, THE PROJECT!!!

I am happy and satisfied. It is warm at home and I don't have to worry about buying fuel and later dealing with it.

The decision to install a heat pump depends on many factors, such as geographical location, type of building, availability of energy sources, and financial considerations. Here are a few aspects to consider when assessing whether a heat pump is cost-effective for you: Geographical location: Heat pumps perform better in areas with a moderate climate, where temperature differences are not too extreme. They are more efficient in operation when the average air temperature is higher. Type of building: Heat pumps are more efficient in well-insulated buildings. If your house is well-insulated and insulated, a heat pump may be more cost-effective.

Well, I don't know... For me, the initial cost is a bit of a barrier, and then there's also the issue of compressor failure. In addition, you need to have underfloor heating and appropriate radiators. As far as I know, some people also complain about the noise. And with Polish, sometimes very low winter temperatures, it may not handle bends well.
