Heating systems and Heat sources - choose the right one for your property
Choosing a heating system for your home is an important decision that requires careful consideration. Today, there are many different heat sources to choose from. The heating system that best suits you depends on your house, plot, and where in the country you live. It's also important to consider price, efficiency, and environmental impact. Install a heating system for your villa that is quick and convenient and contributes to as little harm to the environment as possible.
At Ulma, we believe it's important that you choose sustainable biofuels to heat your home. Therefore, below we will go through several options for heating with biofuels, but also heat sources where fuels harmful to the environment are used.
We hope that through this list of different heating systems, you will be able to find one that suits you and your home.
Oil Boiler - an antiquated heating system
An oil boiler consists of an oil system that includes everything from storage tank to a smaller day tank, a burner, and a water heater. Using an oil boiler as a heating system and oil as fuel has today become a less commonly used way to heat your house.
One reason for this is that the environmental risks of oil burning have received significant attention due to the large amount of carbon dioxide released during combustion. According to the Swedish Petroleum andamp; Biofuels Institute (SPBi), 941,246 m3 of heating oil was delivered to the Swedish heating market in 2016. The climate impact of this oil corresponds to nearly 4 million tons of carbon dioxide, according to the Swedish Environmental Protection Agency's climate calculation. Something that in turn corresponds to just over 5% of the country's total emissions.
The price of an oil boiler as a heating source has also increased significantly in recent years. The installation cost today is around 40,000 SEK. Additionally, there are costs for any waterborne heating systems. The purchase of oil has also become much more expensive. An annual consumption costs at least 30,000 SEK. However, the price may vary.
Advantages of oil boiler:
- Seen as an easy-to-maintain heating system for villas because it requires little maintenance or daily supervision.
Disadvantages of oil boiler:
- The combustion of oil releases a lot of carbon dioxide into the atmosphere. This is a contributing factor to today's significant climate problems. If we were to switch all types of combustion to biofuels like pellets, this would mean significant environmental improvements.
- The oil boiler's tank requires a lot of space as well as a waterborne radiator system and a chimney for flue gases.
- The price of installation and oil purchase is high. The overall costs are therefore large.
Direct Electric Heating
You can heat your house through a waterborne heating system or in this case, direct electric heating. This is the electricity you receive directly to the house via the grid. Here, radiators are used as the heat source, or in some cases, electric coils in floors and ceilings that convert electricity into heat.
Direct electric heating is not considered a viable system for heating houses today. This is due to today's high electricity prices and the fact that the system makes it difficult to change heating systems.
Compared to other types of heating, direct electric heating is the most expensive form of heating. However, the installation is relatively cheap.
How much you need to pay in electricity bills each month is difficult to predict as there are several factors at play. It depends on what the electricity price is that month, but also on how much electricity you consume. Normally, the electricity consumption for an electrically heated villa is around 25,000 kWh per year. Here, heating and hot water consume the most electricity in the home, about 80 percent of the total electricity consumption. The rest is household electricity.
Compared to other types of heating, such as pellets, direct electric heating is the most expensive form of heating. However, the installation is relatively cheap.

Advantages of direct electric heating:
- Cheap to install
- The elements require almost no maintenance at all
- It's easy to control the heat in your home because the electric heat comes on directly when needed and can be easily turned off
- You avoid a wood or oil boiler and a piping system to keep track of
- No procurement of raw materials is needed, such as wood or oil
Disadvantages of direct electric heating:
- Electricity prices are very high today and we do not know what the price of electricity will be in the future
- In some cases, electricity comes from coal, oil, and gas which are non-renewable fuels
- If you have an old thermostat, this can result in uneven heat in the house
- Some types of electricity production are bad for the environment
- If there is a power outage, all heat supply to your home disappears
Pellet Heating - a heat source from bioenergy
Pellet heating is the heating system we at Ulma specialize in. Heating with pellets as fuel is popular among property owners such as houses, industrial properties, and farms. Wood pellets are made from sawdust and cutter chips, which are byproducts. Therefore, pellets are also considered a biofuel. A major advantage of pellet boilers that burn pellets is their minimal environmental impact. Pellets are also convenient to store and burn in a pellet boiler with a pellet burner or pellet stove.
If you wonder which heating system is the cheapest, we want to advocate for pellet heating. Pellets have a high heat value of 5.2 kWh/kg with low ash content, resulting in a consistent temperature in your property. Buying pellets is also very cheap compared to, for example, heating oil or electric heating.
Advantages of pellets:
- In many cases, the lowest operating cost compared to other systems
- Often pays for itself after 3-5 winters, assuming today's prices for electricity and oil
- A renewable fuel and environmentally friendly
- A new pellet boiler requires very little maintenance
Disadvantages of pellets:
- Requires storage space
- Requires some supervision a few times a year
Ulma offers a quality range of pellet heating systems. With us, you will find market-leading pellet boilers, pellet burners, and pellet stoves.
Wood Heating - Tradition and coziness
Wood heating stands as one of the oldest methods of heating homes. For centuries, humans have used wood to create warmth and comfort during cold periods. Today, modern wood stoves combine traditional charm with efficiency and environmental friendliness. At ULMA, we offer a range of wood stoves that not only efficiently heat your home but also serve as an attractive interior detail.
Advantages of wood stoves:
- Sustainability: Wood is a renewable and natural resource, making wood heating an environmentally friendly alternative compared to fossil fuels.
- Cost-effectiveness: After the initial investment in a wood stove and installation, the cost of wood can be lower than many other heating options, especially if you have access to your own wood.
- Aesthetics and comfort: A roaring fire in a wood stove creates an unmatched feeling of warmth and coziness. The design of a wood stove can also be a stylish addition to the home.
Disadvantages of wood stoves:
- Work effort: Preparing and burning wood requires more manual labor compared to other heating sources.
- Storage space: To use a wood stove, you need enough space to store wood, which not all homes have access to.
- Emissions: Although modern wood stoves are designed to minimize emissions, burning wood can still release particles into the air, requiring good ventilation and regular chimney cleaning.
At ULMA, we have a range of wood stoves that meet various needs and preferences. From traditional cast iron wood stoves to modern small wood stoves suitable for smaller spaces.

Heat your house and contribute to a cozy atmosphere in your home with a pellet stove. A major advantage of Ulma's pellet stoves is that they work automatically. It has a programmable thermostat that controls the stove so that the right amount of pellets is fed in, depending on the desired room temperature. When this temperature is exceeded, the stove turns off and goes into low flame mode. When the temperature drops, the stove automatically ignites again. We also have a range of stylish wood stoves, if you're more into cozy warmth.
Solar Panels
Another type of renewable energy source used for heating residential houses and villas, but also public buildings, is solar panels. Typically, solar cells are connected in larger solar panels and are mounted on the roof as a complementary energy source. When the sun's rays hit the cells, an electrical voltage is generated on its front and back. By connecting a wire to the solar cell, current is formed in the form of direct current. That way, your property can be heated.
Even a solar collector is a good complement to a main heating system (such as a pellet boiler). The solar collector does not produce electricity but utilizes the sun's heat. The heat from the sun's rays is used for hot water and heating. With an accumulator tank, the surplus from the solar collector can be stored for times when the sun is not heating.
Advantages of solar panels:
- An overall environmentally friendly heating system
- Requires little maintenance
- You produce your own electricity and thus become self-sufficient
Disadvantages of solar panels:
- High initial investment cost
- Solar energy is produced only during the day
- Leads to indirect environmental impact in, for example, manufacturing and transportation
Geothermal Heating
Geothermal energy is solar energy stored deep in the ground and used to heat our houses. Through a geothermal heat pump, stored solar energy is utilized and supplies your villa with heat and hot water.
There are also ground heat and lake heat that work in similar ways. Which one suits best depends on your house's energy needs, which heating system your villa has today, and the nature of your plot.
Advantages of geothermal heating:
- An economical energy form that helps you save money
- A type of bioenergy with little environmental impact
- Requires very little maintenance
- Can be combined with other heating sources
Disadvantages of geothermal heating:
- Costs a lot to invest in
- High operating costs considering today's electricity prices
- Requires drilling an energy well
- Short lifespan of the pump
- Requires permission from the municipality
