Upgrading from Radiant to Warmboard Radiant

Nevin Lantz is a clinical psychologist who is also very talented in home building and remodeling. This past year, Nevin finished renovating his retirement home in Capitola, California. He had a fantastic experience with Warmboard and was kind of enough to tell us about his experience.


“Growing up in Pennsylvania, we were used to cold winters. My father was a general contractor back then, and I remember when our house was upgraded with radiant baseboard heating. It was a game changer! It was still an early technology at the time but it was such a remarkable improvement from the coal-fired hot air furnace we had been using.  For the next many years I recognized and enjoyed the benefits of living in a home with baseboard heaters. 

Years later in 1972, I traveled to Afghanistan and had the privilege to visit a lovely protestant church in Kabul. And aside from the architecture, one thing I almost immediately noticed was radiant heating, though I could not see baseboard radiators anywhere. Turns out they were heating it through the floor. All the benefits of radiant heat, without the visual reminders on the walls. It was wonderful.

In the 1980s, we bought a 150 year old farmhouse in Pennsylvania. It needed a lot of work. Using all the skills I had picked up over the years, I was able to make the house a home. It wasn’t like building a house from scratch, but it came pretty close. I knew I wanted radiant floor heating, and the only real option at that time was to pour gypsum concrete over the tubing. What a nightmare that turned out to be! First it ran all over the place and made a huge mess. It dried that way, and when the construction crew began breaking it up, they hit the tubing. Even once all that got resolved, affixing the floor was no easy feat.

Still, we enjoyed that home for many years, and even when moving to California to pursue my career in clinical psychology, I continued to remodel my homes while keeping up with the latest developments in the home building industry. It was during this time when I first heard about Warmboard in the trade publications. I remember seeing the thin profile of the panel and its extensive use of aluminum – I immediately made a mental note.

Fast forward and my wife and I are making our retirement plans. We’ve purchased a condo in Capitola, California and know this where we will be spending many years to come. I knew I wanted Warmboard, and now these many months later, I couldn’t be happier. 

I installed the panels and tubing myself, and just hired a plumber to do the final connections to and from the boiler. I got rid of my furnace, and by using the Navien 150 Combi-Boiler, I was able to get 15 square feet back of usable space to our home. The custom routes took a bit of time, but the router bit and template Warmboard provided were immensely helpful. After the systems was hooked up, we installed engineered hardwood over the panels. 

Having 4 separate zones is wonderful so we can have the ideal temperature in each area of our home throughout the day. We can keep our bedroom cool during the day, and turn down the kitchen when the sun shines in. And of course, all this is programmed into our thermostats now, so we can save energy and experience more comfort.

Working with the Warmboard team was so easy. Peter and Todd (Warmboard employees) were always just a phone call away. I was expecting to just order some panels and be done with it, but Warmboard gave me so much more – from detailed, easy-to-follow plans and documentation, to consistent support throughout my installation. The Warmboard team was wholly committed to the success of my project. 

I absolutely love my Warmboard system, there’s just no comparison to the other radiant systems I’ve experienced. My wife and I couldn’t be happier.”

Homeowners Jeremy & Callie, Kansas City

In this Warmboard Works post we talk to Jeremy and Callie, homeowners who are in the midst of remodeling a 100 year old commercial building into their dream home. The West Bottoms Project is not your run of the mill remodel and these innovative DIY'ers are using Warmboard to bring ultimate comfort to this unique project. Bonus – they documented much of their construction in a photo essay, which can be found here:


“There are probably 400 reasons why we chose Warmboard, but I’m sure you’ve heard all of those before! I of course read a ton about the product and thought it would be an amazing luxury to have, but I figured it would actually be a bit too expensive – something I’m sure you guys hear all the time, right?

Our building is in the coolest neighborhood in Kansas City – called the West Bottoms – andwas originally built as a Horse Stable and Warehouse / Carriage House. It’s got a pretty interesting shape that comes from the railroad tracks that ran up to the loading dock doors on both the West and South walls (we have 7 loading down doors).

Because of the size of our building (the first floor is approx 6,000 sq ft), the 10 foot tall basement (also 6,000 sf ft) and the really high ceilings (about 25 feet in the main room), we knew heating the space adequately was going to get interesting.

The ceilings in our building are beautiful. 100 year old wood, amazing trusses and greatheight (probably too high, but whatever!). But having to hang duct work, seeing tubes everywhere would look like a mess and hide a lot of the charm of the building. It would have driven me crazy, and it would look hideous. So from an aesthetic standpoint it just wasn’t going to work.

Also, having hot air blowing down from our high ceilings, coming down to about 8 feet, then making a u-turn and heading back up towards the cold roof? No thanks. I had visions of us freezing on our couch with the roof being a toasty 80 degrees. So forced air wasn’t going to work on a functional level either.

Still, thinking our options were limited, we called in a slew of HVAC/Mechanical contractors. All came back with a horror stories of us needing multiple, monster heating and cooling units (that would go where? who knows.) to blow A LOT of air to POSSIBLY get us to a comfortable temperature. We then slogged through the data and crunched the numbers they gave us and the prices really skyrocketed. Suddenly, the thought of “Warmboard being too expensive” weren’t such an issue any more and it quickly became the best option to heat the building.

My wife Callie and I, along with some family and friends, have done 100% of the installation ourselves (We mostly pay our laborers in a combination of pizza, barbeque and gratefulness)! The plans you provided were amazing! As the project progressed however, there were a few issues with our structure we hadn’t really expected. But that’s the great thing about Warmboard–R – it was really easy for us to make adjustments on the fly, cut custom pieces or execute some custom routes to get around these situations. It’s one thing I really wasn’t expecting. This really is a great building tool! One that’s not meant to snap into place or it’s not going to work, but a panel that provides amazing flexibility in the design layout. The whole process was very intuitive. And anyone can easily grab 2 or 3 panels and carry them to where they need to go. We invested in 6 pairs of knee pads, 4 new drills and a TON of screws and it actually went fairly quickly, all things considered. Especially for a ragtag group like us. Moving forward, we will be hiring a professional to connect the boilers and the manifolds, run tests, etc. But as for all the panels, the tubing – we did all of it ourselves.

Callie and I are coordinating all the work on the job. It’s a monster project, but so far sogood. Things are moving forward quickly and we’re hoping to spend Thanksgiving there this year – just in time for the 100th birthday of the structure. We’ll have everyone there too and are looking forward to being really toasty!”
