In advance of choosing your condensing boiler, most effective for you necessary to determine the desired domestic difficulties production mode: instantaneous (without tank) or by accumulation (with a hot water tank). In the case of the instant boiler, the production of difficulties is done at the opening on the tap. The cold water passes via a heating body, is warmed through the heat of the burner, then kept at temperature over the drawing. On some models with boilers, called indirect indirect generation, the water passes through a plate heat exchanger to become heated.
The advantages of most of these boilers without balloon are many: ecological: only the water applied is heated; source of ease and comfort: hot water is available consistently and in unlimited quantities; sensible: congestion is reduced in the absence of a balloon;
economical: the cost of such type of boiler is generally lower than for a balloon boiler. Be careful nevertheless, because these boilers also have some disadvantages: the temperature depends upon the flow of water; the bigger the flow, the less time the water has to heat up. If you draw while doing so (if someone does the dishes whilst you shower, for example), the water could be less hot than desired;
trouble is not available when the lake flow is too low: the good news is minimum flow to switch on domestic warm water production; in the case of your indirect production boiler, the plate heat exchanger must undergo a regular anti-lime treatment; the burner of your boiler is subjected to frequent start-ups and stops, which speed up its wear.
Also read: The temperature of my hot water is set between 55 as well as 60. The boilers without go up, practical and economic but offering a limited comfort we’ve passed away of multiple draw of difficulties, are suitable in priority for the hearths composed of 2-3 people, or to the people having the ideal space to install a go up.
The accumulation boiler: comfort most notably With a built-in boiler go up or separate boiler, the storage boiler (or go up boiler) can produce and store large volumes of hot water. Two choices are: the coil, or the charge balloon with eating plan heat exchanger. If the performances from the latter are better, it is usually more sensitive to deposits with limestone.
