Frequently asked questions
Heating with electricity?
Compared with the costs of heating with electricity, the cost of heating with biomass pellets in the PETROJET boiler is about 70% lower.
Example: your invoice for electrical heating is £5000 per year. Multiply this amount by the coefficient 0.3. The result is £1500, and this is approximately the cost of your heating with wood pellets in the PETROJET boiler (biomass pellets at the cost of £220.00/t, and calorific value of 16 MJ).
Heating with coal?
When loading coal manually, the efficiency of your coal-burning boiler will be approximately 50% - this means that half of your investment in coal will not be turned into heat in such boiler. Compared with this coal-burning boiler, your consumption of biomass pellets in the PETROJET boiler will be about 30% lower.
Example: If you burn 80 double centners of coal, your fuel consumption in the PETROJET boiler will be about 50 double centners of biomass pellets; for this amount you will usually pay CZK 15,000 (biomass pellets at the cost of CZK 3,000/t and calorific value of 16 MJ).
Heating with gas?
Compared with the costs of heating with gas, the cost of heating with biomass pellets in the PETROJET boiler is about 65% lower.
Example: If your monthly expenditure for heating with gas is 12 x CZK 4,500 – i.e. CZK 50,000 per year, the cost of heating with biomass pellets in the PETROJET boiler will be about CZK 17,500.
Pellet boiler on installment using savings on fuel
Replacing a gas boiler for the PETROJET boiler. Instead of regular payments for gas, pay your gas boiler in instalments and buy fuel. In about three to five years, this investment will return.
Example – indicative calculation: A house with gas heating with the costs of CZK 5,000 per month. After replacing the gas-burning boiler for the PETROJET boiler, your monthly instalments for the PETROJET boiler may be CZK 3,250. With the costs of biomass pellets amounting to CZK 1,750 per month, your total monthly costs will be CZK 5,500. In 40 months, your investment into the purchase of a new boiler will return due to savings on fuel. After repaying the boiler, your total expenditure will drop to around CZK 1,750 per month just for fuel. Your savings will be about CZK 3,250 per month, i.e. CZK 39,000 per year.
Boiler with assembly may be bought on installment
Financing of the purchase of the PETROJET boilers is provided in cooperation with the companies Essox or Cetelem.
