Good to know about combo booths. Here you will find tips on heat boiler with accumulator tank. Firewood boiler and oil boiler in a boiler boiler with combination, a so-called combo.

Combination boiler, boiler and storage tank

In recent decades, all construction and energy scientists have agreed that our heating costs will increase for each year. As a direct contradiction to this security, the total uncertainty about which fuel we will be able to use us in future is the total uncertainty. If you mix these facts, one thing is clear: The self-sufficient homeowner has every reason to take care - for example with a boiler that can be powered by oil and gas as well as with electricity and solid fuels.

This guarantee depends not least on price developments in the fuel market. In the 1980s, for example, many homeowners replaced their oil boilers from electric power because they differentiated the electricity taxes then made the electricity current more interesting in comparison with the price of oil. Nobody can provide any guarantees that we will not face a new turnaround in the future, where gas, pellets or any other fuel we are not aware of will be of high interest. The more possibilities you take into account when installing or replacing a boiler, the easier you can customize, with the natural effect that you can quickly switch to the cheapest possible operation.

A modern combo can look in many ways. For example, it can be completely ready for two or more types of fuels, so that you can choose energy types without complex changes. But it can also be an electric or oil boiler prepared for a later, more or less modest completion with, for example, a gas module or heat pump. A boiler of that kind can be regarded as a base unit in the heating system and is far from any bad solution. However, a prerequisite is that the height and area of ​​the smoke duct are already adapted for combination operation.

Otherwise large intervention may need to be done to meet the more comprehensive safety requirements for solid fuel firing. With the same certainty as we know that we must totally save energy, it is clear that certain periods give an electricity surplus. Since electricity can not be stored, it is logical during such periods to sell power at a lower price than during high consumption. Already a combination of electric and oil boilers makes it possible to utilize these low-priced times. With the aid of a switching time in the electricity distribution meter cabinet, the operation automatically switches from oil to electricity when the taxi is switched.

In addition to these options for saving oil, an advanced heating system can be equipped with a load guard. This reduces the power supply on the electrical side, which means that one can also choose a lower main fuse, which may result in a reduced base fee. When assessing the heating system you need, there are also good reasons to ensure the hot water supply. There is a lot of money to save, without saving beyond comfort.

The drawing shows the principle of a boiler intended for gear operation between electricity and oil or gas and for completion with wood. The switch between the different fuels can be controlled both automatically and manually. The shift requires no change of boiler. Note that the wood burning boiler, which uses reverse combustion, has a ceramic coating.

Future Changes?

Also, find out if there is a gas grid in your residential area. If this is not the case, you may be notified of future gas plans. So far, gas has been available as an energy source almost exclusively around the largest cities, but since natural gas seems to be increasingly interesting, it is possible to expect an expansion of the supply network. All you really need to do to switch from oil to gas is to change the burner. With a well-fitted boiler, the gas gives the same high efficiency as oil. Also note that "gas areas" may be subject to oil-related restrictions.

Environmentally friendly wood burning

If you have access to cheap fuel, or even get the fuel from your own land, there is of course no reason to abstain from that advantage. A combination boiler with the possibility of using fuel as fuel can also be a major advantage in other circumstances. Access to ved-like fuels is one. A serious crisis situation is another. By then it has been used as fuel since ancient times and nobody has until now reflected on possible damage effects. Unfortunately, there are some such - not just soiling but also other more serious air pollution.

However, the technology has improved rapidly after new knowledge. Partly, separate ceramic combustion rooms have been constructed and partly connected to accumulators. The result results in a combustion with such a high efficiency that the emissions of, inter alia, tar and soot with a good margin are under the environmental standards requirements for wood burning in densely populated communities.

Store excess heat in an accumulator tank

Most wood burning boilers are intended for 1 / 3-fire wood length. The process can be described as reverse combustion, in which temperature and oxygen supplement from primary and secondary air is dosed to total balance.

If the fireplace is connected to an accumulator tank, this can save excess heat, especially during wood burning autumn and spring. The accumulators in a system can together contain 1,000 liters of water, of which 100 liters for the hot water supply.

With this capacity, no more than one or two boars per day are needed to keep the house warm and manage the hot water supply. You get 70-80 kilowatt hours of a fully cooked fire. When switching to electrical operation during the summer, the power of an electric cartridge is sufficient for a normal hot water requirement.
