Coal or wood pellets to heat your home? Why benefit can play convenience

In the process of designing your home, it has been allocated, the combustion by an automatic solid fuel boiler. I did not make the firing outside the house, and singled out for this 5,28m2 room with separate entrance (2,2h2,4m).

There also will be located communication: the layout of floor heating, electric boiler (heating provision), and the accumulator water heater, switchboard.

The cost of the boiler with strapping and installation of 200-250 thousand. rub.

The boiler can operate on coal or pellet. Bookmarks solid fuel is enough for 3-5 days (depending on temperature in winter outdoors). In our region, many assemble this equipment in their homes.

But coal is needed for such a boiler fraction, no larger fraction walnut. By large stones worm feed from the hopper jammed.

Prices for high-quality coal sieved fraction non-delivery.

Prices for pellets. They are sold, usually in bags (there are in big bags). They can deliver on his car, if you go along the way by the manufacturer.

And how much you need of coal, firewood and pellets for heating the same area?

Coal, as seen in 2-3 times advantageous not only in price but also advantageous by weight in the preparation of the same amount of thermal energy (smaller or less laying and transportation costs for the period).

But despite the obvious advantage, I know people who fundamentally do not heat their homes with coal, although it is set to automatic boiler hopper.

The reasons they called me two:

1. Coal dust. It gets even accommodation if there is access to the furnace of the house. The dust is deposited in the furnace itself. Working with charcoal - it's a dirty job.

2. Utilization of coal ash. It must be disposed of as waste. In the garden it will not throw as fertilizer in contrast to the ash from the pellets (wood ash - a boon for the garden).

Those. people deliberately overpaid for pellets, just to get a clean and comfortable home heating process. It is worth considering.

It has repeatedly appeared the thought that, heating automatic pellet boilers, despite the efficiency of the boiler, the cost becomes almost as heating by electricity. And worries, you get a whole list:

- order, pay for and pick up pellets yourself, store them;

- monitor their level in the hopper and constantly refilled;

- disposal of the ash;

- if there is no one to monitor the heating - a long winter out of the house does not leave.

On this basis, I had an idea that should be explored heating projects houses the air-to-air heat pump or air to water. According to the cost of the equipment it will be slightly more expensive than automatic solid fuel boiler. But the efficiency and convenience of heating (up -25gr.), He has no equal (COP 8).

Gas main, I do not consider - its in our region will never be. And to save on electricity in the cold - heat a little every day wood-burning stove is not such a big problem.
