Patlite and Pfannenberg: the accident loudly and visibly
The habit of warm water in particular is making itself felt in the summer, when the sultry weather background in conducting prevention hot water, but in a village house or estate warm water does not centrally held.
Therefore the question of “to wash or not wash (yourself and dishes) from the category of classic should go into the practical level (cold or hot), bring in one of the sales offices MPO Electrical and where to stand squarely faced with the choice of a wide range of water heaters (commodity group B98 ) to suit you in performance, electrical characteristics and size.
First you have to think: what to choose. Water Heaters closed connected directly to the cold plumbing lines, work under pressure and feed water to several nearby points (in the kitchen and shower, for example). Units are connected via an open three-way tap to the plumbing for supplying hot water at one point, with the output of water is always open.
Water heaters are instantaneous or cumulative. In flowing water is not retained, only heated when it passes through the heat exchanger – the hotter, less consumption, but quickly, so power consumption is quite high. Used in residential and office spaces with a small consumption: 3,5-5 kW allow in a few minutes to get 1,8-3 liters per minute (for washing and dishwashing). Do not need regular maintenance, but require an additional machine at 32-40 amp, single supply wire in 2,5-4 “square” and grounding. If the computer you are still at 2,5 kW – will have to be replaced.
In the storage units to heat 30 liters of water from 12 to 75 degrees (for washing the family, washing dishes and for a short shower rather) is required from 15 minutes to an hour, 100 liters will warm to 3,5-4,5 hours. On the other hand and cools it slowly, like a thermos (half a degree per hour: it makes sense to heat water at night when counter). You can connect to an ordinary power outlet: even 150-liter water heaters consume no more than 1,5-2 kW. That is, they are particularly good for low water pressure and poor wiring. But the need to periodically clean the heating elements from scale and replacing the magnesium anode, which prevents deposition of salts.
Excess pressure in the tank is discharged through the drainage hole safety valve. And when will block and cold water (temporarily), leakage from the unit prevents the check valve. But if the water in the tank is still not proved, the heater does not burn out due to set its thermostat.
Tankless water heaters usually have a protection class IP 24 (splash, kitchen and bathroom) or IP 25 (on the jets for a shower).
