The existing night storage heaters will be removed and replaced with a gas condensing boiler, which will be installed in the attic. This boiler should also heat the domestic hot water for the house, so a combination boiler if I have researched this correctly.
Such a boiler is currently installed in my rented apartment, which also supplies the apartment below. Unfortunately, the hot water pressure at the taps is rather poor, and I can’t quite determine whether this is due to the boiler itself or the old pipes in the current building. The pressure on the cold water line is okay. There is no storage tank at the moment.
In the house I will fully renovate, the water pipe from the street will be completely replaced, removing the old lead pipe. In the course of this, I want to prevent having weak hot water pressure again, as it is very annoying when showering or filling the kitchen sink or bathtub.
So, what do you think? Is the low pressure caused by the old pipes, or is it inherently due to this type of boiler?
My second question is whether a storage tank is useful for filling a bathtub (e.g., Duravit Paiova) in a reasonable time and for proper showering (possibly with a rain shower). Understandably, I do not want to install a 300-liter (80-gallon) tank in the attic. Are there options around 80 liters (21 gallons), or would the variant of the Vaillant Plus Eco Tec VCI with its 20-liter (5 gallons) stratified loading module be sufficient?
Which standard boiler would you recommend for my plans? I do not need a device that can be controlled via smartphone; it just has to reliably heat about 120 square meters (1300 square feet) of living space in an exterior-insulated timber-framed house and meet my domestic hot water needs. Whether it is Junkers, Vaillant, or another brand is ultimately not important to me, but it does not have to be a premium model (yes, I know cheap and reliable all-rounder don’t usually go hand in hand).
Thank you very much for your help with my planning. Unfortunately, I can only enter the house with my trusted installer at the end of September.
