In recent days we have seen how to spend less on heating, maintain the ideal lighting in winter and ultimately have a more sustainable home, but to achieve this we needed an important point: how to save on hot water, the second energy consumer of our homes, that It represents approximately 25% of total energy consumption.
To choose the most convenient option we must take into account the type of installation we have and also the number of people we are using hot water. A measure that serves everyone is the change from bath to shower, but there are other points to consider, which we can adapt according to our needs, and today we will discover them by the hand of Leroy Merlin.
Solutions for small floors
If you live alone or as a couple in an apartment or in a studio that does not have a gas installation, or if you have a second residence that you use only occasionally, a good solution is to opt for a programmable electric thermos.
These types of devices offer the possibility of savings in consumption of up to 20%. To achieve this we only have to program them so that they are activated in the time slots in which we know we will need hot water and stay off the rest of the day. They also have a echo function which automatically selects the comfort temperature guaranteeing the lowest possible consumption.
Electric heaters like the digital Equation include a isolating material which reduces heat leaks, can reduce consumption by up to 40%. To avoid heat loss, the thermos should be installed, as far as possible, near the bathroom.
It will be enough for one person a 50 liter thermos, for two of 80 liters, for three of 100 liters, for four of 150 liters and for more than 200 liters. Be careful because having a larger electric heater than we need will keep us keeping hot water that we are not going to use, with its corresponding expense. On the other hand for large families it is advisable to consider the possibility of changing to a gas installation, and thus use several showers and faucets at the same time without problems.
What if I have gas?
The thermostatic heaters control the power of the flame through the gas flow, adapting the heat input to the demand for hot water. In automatic ignition heaters such as the Cointra Supreme tobacconist, the flame only ignites when you open the hot water tap, which means a 10% annual savings on gas and also allows you to adjust the temperature.
To choose the most suitable heater according to its production capacity we will have to consider the consumption of hot water, for example: For 1 shower we need 10 liters per minute, but if they are two simultaneous showers or a sink plus a shower, we will need 15 liters per minute, while washing our hands or opening the sink only 5 liters per minute.
The taps are also important
As we have already commented, the ideal is that the thermos be as close as possible to the rooms where we use hot water, but sometimes they are several, or there is no space other than in the kitchen, for which it will help us to have good insulation, both of storage tanks and installing shells in the pipes.
The types of tap also contribute to saving in hot water, apart from checking that they have no losses and controlling the opening of the flow with a reducer, choosing a single lever model will make it easier for us to regulate the temperature without wasting hot water. Try to leave it closed always in the position where the water comes out cold, this is easier with the cold central opening lever, which when opened in a central position gives us cold water instead of warm.
For the shower it is very good to have thermostatic taps They have two controls, one to control the temperature in degrees and another to regulate the flow, keeping the temperature constant even if other taps are opened in the house. They take less time to heat and not having to wait so long to regulate the ideal temperature (between 30 and 35º C) saves all that water that we usually run to get it.
On the website of Leroy Merlin you will find a complete guide to saving water and energy as well as everything you need to reduce spending on hot water. If you start implementing these recommendations now, you will surely notice the difference in the bill at the end of winter.
