Floor heating system

A viable alternative to conventional radiator style heating systems is in-floor heating. A typical solution consists of small-bore pipes, laid in the concrete slab under the floor’s surface. The solution is typically fed by a condensing boiler or district heating.

Heating buildings in this way provides a consistent, even heat release from floor level. It provides comfort underfoot and pleasant temperatures. As the pipes are hidden, there are no unsightly radiators. It also uses a lower water temperature to maintain the same room temperature level as radiator systems.

For the sake of comfort, the floor’s surface temperature should ideally lie between 25-32 °C. This is a relatively low flow temperature. The obtainable temperature difference will therefore lie between 10-15 °C, which is lower than within radiator systems. Floor heating systems thus use a smaller water flow to achieve the same temperature results.

Because condensing boilers work more efficiently at lower temperatures, pairing an in-floor heating system can reduce heating costs. A condensing boiler runs in the more cost-efficient condensing mode at lower temperatures, which saves money. In-floor heating is also well-suited for usage with solar heating and heat pumps.
