We do not represent our life without hot water. Without it, you can not take a shower, soak in the bathroom or just wash the dishes in the absence of a dishwasher. Not all apartments are adequately supplied with hot water and sooner or later each owner faces the question of how to make hot water constantly. The answer is usually one - to warm the cold.
Electric water heaters for apartments
Agree that heating the water with a boiler or on a gas oven is not very convenient, so an electric water heater comes to the rescue. Water heaters are of two types: accumulating and flowing. The difference between a storage heater and a flow heater is that the first heats a large mass of water (30-100 liters) for a long time, while the flow heater heats only a small amount of water that passes through the pipe at the time of use. It is clear that the faster it is necessary to heat water, the more powerful the heater should be.
This is the reason for the prevalence of storage water heaters - boilers , they do not require powerful wiring and can be installed even in old houses, while flow requires modern powerful wiring. The principle of running a running water heater is based on heating the closed electric spiral-TEN running along the water heater. Special automation includes a flow-through water heater for an apartment only when you open the tap, followed by a water pressure sensor. The heating temperature regulator regulates the strength of the electric current passing through the heater and thus makes the water warmer or colder.
The power of the instantaneous water heater depends on how much water you want to heat per unit of time. For example, to wash dishes you need quite a bit of water, and accordingly a low-power heater, but fans will get stuck in a big bathroom or take a shower and have to install a heater more potently, because we can not wait for the bathtub to be full.
How to choose a running water heater?
To begin with, you still need to decide what it will be used for, only for the kitchen, for the shower, or we want to simultaneously prepare a hot bath and wash the dishes.
A flow-through water heater for a kitchen can be the least powerful, but how? In other words, how much electricity does the water heater consume per hour, and how much water can be heated per minute. First, we learn how much water we want to heat up. The flow of water is measured in liters, how much water flows out of the tap in a minute, such is the flow of water. Open the faucet in the kitchen the way you open it, when you wash the dishes, put a liter jar under the jet and note the time. How many liter cans per minute was accumulated - this is how much water you need.
Heaters of 3-3.5 kW capacity can heat 1.5-2 liters per minute, 5 kW - about 3 liters per minute, 7 kW - up to 4 liters per minute.
But the water heater for the bathroom is better to put the maximum power, which will withstand your wiring. To assess the wiring power, it is better to use the help of a professional electrician. He can also be entrusted with the connection of a flowing water heater to the wiring. But how to connect a running water heater to the water supply system - the plumber knows best, perhaps you will need welding work if the pipes in the apartment are metal.
