house photovoltaic heating. Can it be done?
When compared to utilizing the conventional gas boiler, is it beneficial or not? How much gas should I use to cool the rooms and how much does it cost? On the other side, how much did the electric kwh that was charged cost? How much is the one that is self-generated using photovoltaics?
These are the primary concerns that people have when beginning to consider rooftop solar as a helpful tool for reducing energy costs, especially when it comes to winter heating.
First things first: heating a room with PV implies heating it with electricity as well, if not exclusively. So, generally speaking, but not always, it is referred to as electric heating.
Heat pumps, auxiliary heating systems with "electric resistors," infrared heating (illustrated in this article), and other heating methods can all be operated with electricity. The traditional heating system can also be served by electricity by electrically heating the water that feeds the "traditional" radiators in addition to the water heated by the boiler.
The traditional gas heater ends up costing well over a thousand euros a year for domestic hot water and winter heating for a tiny two-room flat. It is challenging to provide an accurate estimate because the cost and consumption depend on so many variables, such as the number of occupants in the home, the location where they reside, the apartment's surface area, "comfort habits" (making 19°C comfortable is one thing, making 22°C comfortable is another), the degree of insulation in the home, etc. Despite this, those who heat their homes with gas (or oil) have a good sense of their annual heating costs.
If properly exposed, one can replace the conventional gas system with a photovoltaic-powered electric system by installing a solar system. Where is the comfort? The benefit is found in how much less expensive solar energy is per kilowatt-hour than natural gas is per metrocube (or diesel oil, which requires even more expense).
Using a photovoltaic system for heating
Using a photovoltaic system for heating
You may use all of the power generated by your solar system for space heating by installing an electric heating system, such as a traditional electric radiant aluminum radiator that can be hung on the wall.
One will be able to maximize photovoltaics' ability to produce energy on their own by employing electricity.
The same is true for heating systems that employ heat pumps, which are now the most well-liked and commonly used. In this instance, only the boiler has to be replaced instead of the entire home's system. The heating source varies, but the heating system is still one that uses water. There are currently a number of intriguing products on the market that incorporate heat pumps with photovoltaics. Indeed, they are frequently the most sensible and cost-effective solutions that can be put into place fast and at a cheap price. In any event, the cost is recovered in a few years. The repayment period is then further shortened when tax deductions are taken into account.
Does using a heat pump with photovoltaics for heating make sense? What benefits?

Photovoltaic heating is cost-effective.
Since it uses around 70% less energy than conventional electric boilers, the heat pump is already an energy-efficient electrical system. When paired with a solar system, the energy and financial savings can exceed 100% because the few kwh required can be replaced by a modest photovoltaic system.
In this manner, solar heating might be a great method to save money.
Installing a heat pump to utilize all the surplus energy produced by the system is an instant and cost-effective option for those with renewable power output, or excess production. Utilizing a solar-powered heat pump can save gas and electricity costs by up to 100% in some cases.
The conventional usage of a solar system does reduce the cost of the bill, but it does not provide the recovery of any extra energy that is produced and put back into use. How can we utilise this surplus without turning it over to the grid? exactly by heating the home's water and interior spaces using a heat pump.
A heat pump uses roughly 550 kwh of electricity, which is about 70% less than a regular electric boiler, to create and store thermal energy beginning with photovoltaics. A typical household boiler uses about 1,600 kwh for an average family.
The standard electric water heater will use roughly 1,600 kwh at a cost of about 360 euros, assuming an average household of 2.6 persons and an average power cost of €0.22/kwh. With the same performance, the heat pump water heater uses just 550 kwh, costing 125 Euros. The annual savings come to roughly 235 euros.

The highest savings are often realized when traditional radiator systems are scaled enough to work at these (such low) temperatures. These savings are between 20 and 40 percent as compared to utilizing a gas boiler. A heat pump can heat water down to 55–60°C. As an alternative, the pump can function in conjunction with the current thermal system.
In radiant systems and radiator (or fan-coil) systems, the heat pump may always take the place of the boiler if it is sized to function efficiently below 50–55°C water temperature. The usage of a heat pump can be substituted for the conventional gas boiler in a heating system by those who so want, saving money on energy expenditures while improving living conditions.
In any case, interventions and replacements need to be set up in accordance with the kind of house, the kind of current system, and the amount of consumption.
