Why Hydronic Heating Feels Different
Forced-air systems heat air, which rises to the ceiling while floors stay cooler. Hydronic radiant systems heat surfaces and people directly — the room feels warmer at a lower thermostat setting, with no drafts, no noise, and no redistribution of dust through ductwork.
Hydronic System Types We Install
- In-floor PEX radiant (slab) — PEX tubing embedded in concrete. Ideal for new construction, additions, and garage slabs. Operates at 35–45°C water temp.
- Above-subfloor thin-slab — Lightweight gypcrete over PEX on existing subfloor — retrofit option with minimal disruption.
- Staple-up under-subfloor — PEX with aluminum heat plates attached to underside of existing subfloor — least disruptive retrofit.
- Hydronic baseboard radiators — Fin-tube baseboard units, independently zoned. Effective for whole-home hydronic without in-floor work.
- Combination systems — Radiant floor in main living areas, baseboard in bedrooms — capturing comfort where it matters most.
Our Process
Free design consultation
We assess your floor construction, heat source options, and zoning requirements before recommending an approach.
System design
Pipe spacing, water temperature, zone layout, and heat source specification — designed to your specific home.
Professional installation
PEX tubing, manifold assembly, circulator pumps, zone valves, and controls — installed to specification.
Commissioning & balancing
System filled, purged, and balanced. Each zone tested for correct flow and temperature response.
Pricing & Financing
Single-room radiant: $2,500–$6,000. Whole-home new construction: $15,000–$40,000+. Free consultation — we assess your specific situation and recommend the most cost-effective approach.
Why Choose Malek
Expert Hydronic & Radiant Heating
New Build & Retrofit
We work on both new construction radiant slabs and retrofit installations in existing homes.
Heat Source Agnostic
We match the right heat source — high-efficiency boiler, heat pump, or combination — to your specific system design.
Zoning Expertise
Multi-zone control for different rooms on different schedules — the defining advantage of hydronic systems.
Long-Term Economics
15–30% better energy efficiency than forced-air plus no duct losses makes hydronic a compelling long-term investment.

Common Questions
Frequently Asked Questions
Can in-floor radiant be added to an existing home?
Yes — the method depends on your floor construction. Slab homes can have tubing in cut grooves. Wood subfloor homes use above-subfloor thin-slab or staple-up systems. We assess your construction and recommend the most cost-effective approach.
What floor coverings work with radiant heating?
Tile, stone, and concrete work best. Engineered hardwood works well with careful temperature control. Solid hardwood and carpet can be used but require specific design parameters. We specify the correct water temperature for each floor covering type.
How much does radiant floor heating cost?
Single-room: $2,500–$6,000. Whole-home new construction: $15,000–$40,000+ depending on floor area, heat source, and zoning. Operating costs are generally 15–30% lower than forced-air for equivalent comfort.
How does hydronic compare to forced-air for efficiency?
Hydronic systems typically achieve 15–30% better energy efficiency — you achieve thermal comfort at 1–2°C lower thermostat settings, and there are no duct heat losses (which can account for 20–30% of forced-air energy in homes with ductwork in unconditioned spaces).
