"Pipeworx was hired to remove an old water heater and replace it with a tankless one in our summer cabin in Pagosa Springs CO. We were not there (in Arizona) so all communication was via phone, text and email.. Walt and Jodi kept us apprised of every step from product selection to installation. We arrived after the install was complete and met with them where they described every detail of the job. Communication is key to any long distance or local work and Pipeworx delivered in spades - the work was excellent and we are using them for another project."

"I'm so impressed, contact was made in a short amount of time.the first response was do you have water, that was the kindest thing to ask. He was concerned that our main line had broken and we had to shut off the water. A genuine concern I really appreciate that. An estimate was given and a day and time to do our job was agreed upon. That morning, I received a phone call, they were on there way. Plastic was placed on my floors, and work began. The crew was very respectful and kind. It was an all day job, they ran a new water main from The meter to our house, it was a huge distance 262 feet. I was amazed at how quickly the team worked, cooperation between the team was quite professional. By the end of the day I had water, a new main line, and a super clean driveway. The crew was proud of there work, and they have good reason to be. A job well done. This is my go to plumber, my knights in shinning armor. I just can't rave enough. Thank you so much"

"Outstanding family-run company. Efficient, professional, reliable, and friendly service. Jim personally handled my plumbing "emergency" on very short notice, and he absolutely exceeded all expectations. I had a saddle valve - connected to the water heater - fail, and he not only fixed the leak but installed a stronger valve/line to mitigate the risk of another premature failure. Jim Needham Plumbing is a top-tier company that goes above and beyond, and stands behind their work; this is the type of small business I am happy to support and recommend to friends and family."

"Aether Mechanical is a great contractor: knowledgeable about HVAC design, competent about installation (and nuances for our home), and responsive at the office. Nicolas, the lead engineer, went out of his way to help us with a noise problem (that his work did not cause) after the boiler installation was complete, and he stayed with it until we all found a solution. Great work!"

"Like any plumbing job today, the cost of installation is rough two or three times the cost of the item. This is a product of shortages of skilled help and there is little to be done. If you want it done particularly with any speed you will pay these prices. The cost of a water heater installed is three times what it was only ten years ago."

Install Boiler questions, answered by experts

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).
