Wood-burning fireplaces, electric fireplaces, bioethanol fireplaces, and steam fireplaces – which is the best choice, where, and when?

When we think of a fireplace, we generally think of a wood-burning fireplace. Naturally, this is for a reason, as we have been burning wood in fireplaces for centuries. Nowadays, fewer people can do this, as in many cases we do not have the option to change the characteristics of a given apartment, or we simply do not have the time to deal with wood-burning. On the other hand, many people have a romantic desire for the sight of a burning fire, or they wish to experience the radiant heat of a fireplace.

.

Let’s take a look at the advantages and disadvantages we need to consider when choosing between the experiences provided by a wood-burning fireplace, pellet fireplace, gas fireplace, electric fireplace, bioethanol fireplace, or steam fireplace:

Installing wall heating in an already inhabited apartment, under plasterboard or stone porcelain – do it yourself method

We can increase our comfort while simultaneously reducing heating costs.

It is well known that the lower the temperature of the water used to heat the house by our boiler, the more economical it is. This is especially true for condensing boilers. Whether it’s an old open fire or a turbo gas boiler, caution is needed because the return water temperature to the boiler must be higher than the dew point of the flue gas. This is approximately a threshold value between 55–60 degrees Celsius. In condensing boilers, the key is that the return water temperature is as low as possible, as the condensation of the flue gas below the dew point is stronger, meaning the precipitation of water vapor from the flue gas. This precipitation, the change of state, comes with additional energy release. The lower the temperature of the water used to heat our home, and by better dissipating this heat, making the return water as low in temperature as possible, the better efficiency we can achieve in operating our condensing boiler.

Here, the heating pipe is already in the living room wall:

All of this is fine and good — however, the lower the temperature of the heating water, the more difficult it is to give off heat, as the temperature difference between the room temperature and the advancing water temperature becomes smaller. This problem can only be solved by increasing the surface area of the heating element. Beyond a certain size limit, implementing this with a radiator would be impractical. Especially considering that multi-panel radiators increasingly enhance heat dissipation through convection (i.e., by heating the air) and to a lesser extent through radiation. This is not advantageous, as heat emitted through radiation provides a more pleasant sensation even at lower temperatures.

On the other hand, if we use underfloor, wall, or ceiling heating, we can heat a larger surface area. This warm, radiant heating ensures a comfortable feeling of warmth.

If we want to live in the apartment during heating system improvements (now specifically discussing water heating), among the three surface heating methods, wall heating comes with the least dust, clutter, and inconvenience, using the following method — provided there is available wall space. And there was.

Energy cost reduction in an apartment block – DIY – window replacement, internal insulation, underfloor heating

Two basic principles:

  1. Produce the energy with highly efficient equipment!
  2. Don’t let the generated energy go to waste!

The transformation of the living room:

.

As much as it’s a priority to steer the population away from gas consumption, let’s admit that in an apartment block without district heating (central heating), heating and hot water can primarily be provided by gas, and secondarily by electricity. If many people switched from gas to electric heating, it would also cause problems, as many apartment block infrastructure and stairwell electrical systems are not designed for mass electric heating. Therefore, the possibility of massively increasing the amperage of apartments would also face limitations. Naturally, heating with air conditioning could be an alternative to direct electric heating, as it represents roughly a quarter of the electrical load, but many people do not like the warm air blowing, and the numerous outdoor units attached to the façades are already a terrible sight. For this reason, I believe gas will remain predominant to a greater extent.

But what can we do to keep our gas bill low?

Do-it-yourself home renovation – window replacement, internal insulation, heating modernization, new bathroom, kitchen, wardrobe – cold and warm flooring

Besides general home renovations – such as replacing cold and warm flooring, kitchen cabinets, and sanitary ware – a crucial point was to create a low utility cost home.

.

Because of this, modern plastic insulated glass windows with shutters were installed, and the previous convector heating, open combustion bathroom heating, and the open flow-through domestic hot water unit were replaced with a single condensing boiler.

Since there is zero chance for common facade insulation in the apartment building in the near future, 10cm thick glass wool internal insulation was installed on the enclosing walls, with a vapor barrier heat reflective foil and drywall covering.

Before you buy a stove, fireplace, or stove-fireplace due to rising utility costs — it’s good to know…

Due to the increase in utility costs, many people are considering wood heating as a replacement for gas and electric heating. In reality, it’s normal to think about winter heating in the summer, but most people seek a solution in winter when the trouble has already begun. Be careful not to focus only on cheaper offers. With quality and attention, you can save on firewood. Wood heating can be economical, but it can also be environmentally polluting and wasteful.

When selecting our wood-burning device, it is important to consider the following:
