I was wondering if anyone would be able to say, what size of pump is the most suitable to my new house.
I have been thinking about buying Nibe 1220 (=1230 in Sweden), but I am not so confident that Finnish pump dealers know how to calculate the optimum size of pump and hole for my house. In Finland the knowledge about optimum sized pump is not yet at the same level as in Sweden, so I thought I would ask you, because you are more experienced.
As I told before, I am building a new house at the west coast of Finland. House is a "concrete" house, made of Siporex. There is 163m2
garage). Volume of the building is 630m3
there are two showers and no bath tubb. Four or five people will be moving in when finished. The is also a fireplace, but mainly for decoration purposes. Ventilation is done with machine where is water based pre warming system.
Finnish dealers have calculated very different size of pumps and holes with these same informations depending of pump manufacturer. Examples:
Nibe 1210 - 5,
IVT HT+ C7,
Carrier heat60 C7,
Thermia Dipl. TWS 12.
so there is guite a wide range of pumps
Hole depths are also rangeing from 150m to 210m.
What is your opinion? What size of pump should I buy? and what size of hole it requires?
Please answer in English. My Swedish is terrible, if possible worse than my English
