System comparison
Electric Heating vs Hydronic
A clear comparison of the two underfloor heating approaches AQUAPROCESS designs with Danfoss components - so you can match the system to rooms, scale, and heat source.
Side by side
Differences in the two installations
Electric and hydronic underfloor heating both warm the floor, but they differ in how heat is generated, how the system is installed, and how it is operated day to day. Use the comparison below, then the selection guidelines that follow.
| Difference | Electric | Hydronic |
|---|---|---|
| Heat delivery | Heating cable or mat powered by electricity under the finished floor | Warm water circulated through pipe loops under the finished floor |
| Plant and equipment | No boiler, heat pump, pumps, valves, or headers required in the floor zone | Needs add-on plant such as a heat pump or boiler, pumps, pipelines, valves, and headers |
| Zoning and usage | Smart zoning is standard - heat only the rooms or zones in use | Typically runs as a larger whole-system load; true electric-style zoning is not available |
| Response time | Faster heat-up after switch-on | Longer start-up unless the system is kept constantly on |
| Maintenance | Fit-and-forget style with essentially zero day-to-day maintenance | Needs regular and periodic maintenance of plant and water circuits |
How to choose
General guidelines to select a system for your requirement
Match your project conditions to the column that fits - then read the reason.
| Electric | Hydronic | Reason |
|---|---|---|
| The entire installation will rarely be on in one go. This will mostly be used in parts i.e. only a few rooms in the entire complex require heating at a time. | Most of the time, entire installation will be ON in one go i.e. the whole complex will require heating almost at all times. | Smart zoning, that is a standard feature of Electric, is not possible in Hydronic Heating. In electrical, only the energy required for the required zone will be consumed, while in hydronic almost the same amount of energy will be consumed irrespective of the usage. |
| You want quick heat-up response time and be able to feel the heat within a short period of switch on. | You have plenty of lead time to start the heating before you use the premises or it will be constantly ON. | Unless constantly ON, hydronic requires long start-up time. |
| You want zero maintenance, fit-and-forget installation. | You are okay with regular day-to-day and periodic maintenance, whatever be the cost or the involvement. | Hydronic needs maintenance, both regular and periodic. |
| Your location is already in an electrified area - public Electricity Board connection is available. In fact, if electricity is available, you must go in for electrical only, leaving aside all other considerations, and it will be a right decision from all counts. | You are in a remote area without public electricity availability. | Cost and involvement in getting authorities to provide you a heavy connection from a far location could be too prohibitive. |
| Not interested in heavy add-on equipment like heat pumps, boilers, pumps, pipelines, valves, headers, etc. | Either okay with the add-on equipment or most of it already exists and can provide the additional heat load required for underfloor heating. Still, the headers and the interconnecting piping cannot be avoided. | Hydronic is based on add-on equipment. It will take lots of capital cost, maintenance headaches, space, interference with architectural designs, placement adjustments, besides heavy running costs. |
