Hydronic Heating

Boiler-fed radiant heat — repair, maintenance, and new zones

Radiant systems are uncommon in new construction but still run in older Carlsbad homes. We service the boilers, circulators, and zone valves that keep them working.

Homeowners who switch to radiant heating typically cut their energy bills by 20 to 30 percent. That's not marketing fluff. These systems heat from the floor up, warming objects and people directly instead of blowing hot air through leaky ductwork. Less heat loss means lower bills. And in a mild climate like Carlsbad's, radiant heating is especially efficient because it doesn't need to fight extreme cold to keep your home comfortable.

Radiant heating works by running warm water through PEX tubing installed beneath your floors. That's hydronic heating, and it's the most common and most efficient type for whole-home use. Electric heating mats are another option, mainly for single rooms like bathrooms. Jack's Plumbing and Heating installs, repairs, and maintains these systems for Carlsbad homeowners, and we've been doing it for 35 years. Heating is in our company name for a reason.

What homeowners get

Radiant heating installation and repair in Carlsbad, CA. More efficient than forced air with no ductwork needed. 35 years experience. Call (760) 750-2626.

Circulator pump failure is the most common call

When a zone stops heating, the circulator pump is the first suspect. We carry common Taco and Grundfos replacements.

Zone valve diagnostics for uneven heating

If one room heats and another doesn't, the zone valve actuator may be stuck or burned out. Electrical testing confirms it in minutes.

Boiler pressure and expansion tank checks

Low pressure, frequent relief valve discharge, or air in the lines all point to expansion tank or fill valve issues. Annual service prevents winter failures.

New radiant zones added with PEX

Extending a radiant system to a bathroom addition or garage conversion is possible with PEX tubing tied into the existing boiler loop.

How It Works

How Radiant Heating Installation Works

Heating is in our company name for a reason. We design, install, and repair hydronic systems for Carlsbad homeowners.

Evaluate layout and flooring

We assess your home's floor type, room configuration, and existing heating to design the right system.

Size the boiler and plan tubing

Square footage and zone count determine boiler capacity. We map PEX routes for even heat distribution.

Install PEX and connect to boiler

Tubing goes beneath the flooring and ties into the boiler loop and manifold. Each zone gets its own valve.

Pressure test and dial in temps

We fill the system, bleed air from every zone, and set temperature controls room by room.

What to Know

What Makes Radiant Heat Worth It

Forced air pushes hot air through leaky ductwork and blows dust around. Radiant heat has none of those problems.

Even warmth from the floor up

No cold spots, no ceiling-level heat pockets. Warmth starts at your feet and rises naturally.

Completely silent operation

No fan noise, no whooshing through vents, no furnace clicking on and off at night.

20-30% lower energy bills

No duct loss means less wasted heat. In Carlsbad's mild winters, the system barely works hard.

Better air quality for allergies

No dust, dander, or allergens blowing through the house every time the system runs.

PEX tubing lasts 30-50 years

Minimal moving parts and no filters to replace. Long-term costs stay well below forced air.

Deep Dive

Radiant Heating Makes More Sense Than You Think

Carlsbad winters are mild but still cool enough to run a heater from November through March. Radiant systems thrive in this climate because they don't have to fight extreme cold.

Forced air systems lose 20 to 30 percent of heated air through ductwork before it ever reaches your living space. That's energy you're paying for and never feeling. Radiant heat eliminates duct loss entirely. Warm water circulates through PEX tubing under your floors, heating objects and people directly instead of blowing hot air toward the ceiling.

For bathroom and kitchen remodels, heated floors are one of the most popular add-ons we install. There's nothing like stepping onto warm tile on a cool January morning instead of cold tile that makes you flinch. It's a small upgrade during a remodel that adds real comfort and resale value.

FAQ

Frequently Asked Questions

Clear answers on scope, pricing, timing, and what to expect before work starts.

Is radiant heating worth it in Southern California?

It is. Carlsbad's winters are mild but still cool enough that you'll run a heater from November through March. These systems use less energy than forced air because there's no duct loss, and they heat at lower water temperatures. In a mild climate, the system doesn't have to work hard, which keeps operating costs low year after year.

Can radiant floor heating be installed in an existing home?

Yes, but it depends on the flooring. It's easiest to install during a remodel when floors are already coming up. Tile, stone, and engineered hardwood work best over the tubing. We evaluate your home and let you know what's involved. Bathroom and kitchen remodels are the most popular retrofit projects we do.

How much does radiant heating installation cost?

Costs vary based on square footage, flooring type, and whether you need a new boiler. Expect $6 to $15 per square foot for hydronic systems, including materials and labor. A bathroom addition might run $2,000 to $4,000, while a whole-home system is a bigger investment. We provide free estimates with detailed pricing.

How long does a radiant floor heating system last?

The PEX tubing itself can last 30 to 50 years with proper installation. The boiler typically lasts 15 to 20 years. Maintenance is minimal compared to forced air systems because there are no filters to change, no ducts to clean, and fewer moving parts overall. We service boilers and can replace them when the time comes.

Does radiant heating work with all types of flooring?

Tile and stone work best because they conduct heat efficiently. Engineered hardwood is also a good choice. Solid hardwood can work but needs careful moisture management. Thick carpet insulates against the heat and reduces the system's effectiveness. We'll advise on the best flooring options during your free consultation.
