How to choose a towel rail
A towel rail in the bathroom does two things: dries towels and adds local comfort heat. If you choose only by the “nicest chrome”, you risk a hydronic model with no heating connection — or electric where there is no safe socket. This guide organises towel rail choice. Comparison: electric or hydronic. Heating map: heating and hot water. Step 1 — hydronic or electric Hydronic (from heating)Electric WhenThere is a heating circuit / renovation with a connectionNo convenient heating line; need it in summer too PlusHeat “from the system”Independent of heating season MinusSeasonal; needs..

Radiator valves — what to choose
Radiator valves are how the radiator “listens” to the room. Without a valve and thermostatic head you only regulate heat via the boiler/whole system — less comfortable and often costlier. This guide teaches choosing valves by connection and job. Radiator: how to choose a radiator. Thermostat logic: what a thermostatic valve means. What is in the kit Thermostatic valve — mechanism that closes/opens flow. Thermostatic head / sensor — the “head” that feels room temperature and drives the valve. Return / shut-off valve — lets you isolate the radiator for service and balance. Often you ..

How to choose a radiator
A radiator is a heat “window” in the room: through it heating water gives heat to the air. If you choose only by the “nicest white rectangle” or the longest mm, you risk a cold room or a unit that does not fit the niche. This guide teaches how to choose a radiator step by step — then look at concrete models in the inventars.lv range. Heating map overall: heating and hot water. Besides the radiator you often also need valves and sometimes a circulation pump. Start with three questions How large is the room and how well does it hold heat? A corner room with large windows “eats” more heat ..

How to choose heating and hot water
Heating and hot water in the catalogue often looks like “all warmth on one shelf”. In reality there are at least three jobs: heat the room, heat water at the tap and bathroom comfort (towel rail). If you buy “something warm” without a job, you risk getting a boiler where you needed a radiator — or the other way round. This guide is a map. Go deeper via the links. We skip prices here — type, size and connection matter more.

Tonga: black, chrome. Eros: chrome, black, liquid soap. Mixer before accessories: guide. Basin: basin. Towel rail (if needed): towel rail.

How to choose a bath and shower
