There is no requirement to “install precisely”, the decision is made by the client personally. However, in the absence of a device that ensures the circulation of the coolant, be prepared for the fact that the system will be colder at the end, the system will take longer to warm up, and fuel costs will increase. So our advice is to immediately buy and install the pump, thereby avoiding unnecessary expenses. Moreover, the device pays for itself quite quickly.

Cast iron and metal pipes are a thing of the past, plastic (polypropylene) is more popular and for good reason. Polypropylene pipes last more than 50 years, do not rust, are cheaper, easier to install and can be connected to any type of radiator without any problems.

In order to avoid buying a separate boiler or flow-through heater for hot water, you can install a double-circuit boiler, which will solve both problems: heating and hot water supply.

For the climate of Ukraine, a heat source power of 1.1-1.2 kilowatts per 10 m2 with a ceiling height of 2.5 m in the room is sufficient. However, it is more appropriate to calculate the boiler characteristics individually, taking into account the features of the object. For example, if the house is insulated, equipment with a lower power may be sufficient for heating. Today, the choice of boilers is huge; if desired, you can choose compact, but at the same time effective climate control equipment for a small room.

Yes, in such a situation we recommend connecting the gas and solid fuel boilers in parallel if possible. If such a connection is not possible, then with a series connection it is necessary to install the gas appliance after the solid fuel one in the direction of the coolant flow. With this solution, less fuel will be spent on heating the air, which literally flies into the pipe.
