Gas boilers

Gas boilers are compact and efficient - they require little space and even the most powerful units can be wall-mounted. Using gas, especially condensing gas boilers, it is possible to achieve high operating efficiency and, unlike pellet or wood boilers, they do not require constant care - as long as the gas supply is in order, their operation can be fully automated - no constant topping up is required (except when using your own gas storage, but even then this process is less frequent than for pellets). Disadvantages include the need to build a gas pipeline if one does not exist, and the variable cost of gas.
