Close-in boiler and teruglevertarief
Posted: Tuesday 23 July 2024 22:23
In the Netherlands a new electricity tariff has been introduced for returning energy to the net.
This makes it profitably to return less energy to the net.
One can charge a battery, one can charge a car battery, one can wash during sunny hours in summer and more.
I am thinking about the following usercase.
In our house there is a distance of about 3-4 meters between the gas boiler and the kitchen tap.
To get warm water in the kitchen one has to wait 10-20 seconds in which time only the water pipe will be preheated at the cost of expensive gas without getting the warm water out of the tap.
I'm thinking about installing a close-in boiler which will heat the water using PV power. (if enough PV energy is present)
Problem is that these close-in boilers have an electric element of 1500 Watt.
How nice it would be to make the element use 500, 1000 and 1500 Watt or maybe even 250 Watt to heat up the water.
Even nicer if this close-in boiler would have a bypass to use gas-boiler-heated water in case the temperature inside the close-in boiler is less than 40˚C.
I think this is an economic way to use self produced energy directly for own consumption.
Other measures:
- Car battery charging at times when high PV output is present.
- Temporary switching off air to air heat exchanger while water cooker or oven is using electricity
Balancing power consumption in house is rather easy with dzvents.
I asked boilermarkt.nl: there are no close-in boilers available where one can regulate power consumption.
Share your thougts here please.
