"It started off bad because I had the water heater installed, submitted my paperwork for my rebate for the installation and then my rebate ended up not getting honored because the water heater that was installed didn't qualify for Spire's rebate. Turn's out that the water heater that would fit my location as well as satisfy Spire's rebate, I would have had to wait 5 to 6 weeks for that specific water heater so, the owner of Hosack's Plumbing cut me a check for the amount of the rebate and the amount over time that the new water heater would have saved me. Not the perfect situation but, that was a win win for me as well as Hosack's Plumbing because a good water heater was installed just not one that would quite fit the Spire requirements for the rebate! Hence we didn't need to take a brand new water heater out and replace it with another water heater that was just .05 UEF Higher!"

"A couple of years ago this company installed my tankless water heater
and I really liked the owners Andy's professionalism. We were having
problems with the water heater and Andy sent some of his workers out to
fix the problem right away.
I referred this company to a friend of mine because of the great experience I had, she used them and they were even able to do a couple of other things around her house that was in the scope of their work.

"Last December, on one Friday early evening, I noticed my heating system was not working and it was very cold. I called PHCS services and they sent a technician Saturday morning to diagnose the issue. FYI, I am a handyman and fix a lot of things around my house, but I don't have the right tools for this service and don't like to do anything with gas pipes. I watched the technician doing his work and realized he is an expert. He checked everything and was able to detect that the gas valve was the culprit. He also recommended replacing the pressure switch. He explained to me what was happening and even showed me how the failure was triggered. In addition, he checked the whole system and even recommended me to install two carbon monoxide detectors, one by the heating system and one on the first floor by the bedrooms. I haven't bought and installed them yet - mea culpa. He didn't have the parts in his truck, but he said, Monday morning another technician would come with the parts and replace them. Before leaving, he explained to me that I could turn on the heating system for a few minutes to heat the house until the pressure valve would fail. After that, I would need to wait sometime and then could turn on the system again. I followed his instructions and was able to stay and sleep in a warm house on Saturday and Sunday. As promised, Monday morning, another technician came over, replaced the parts, and made the necessary calibrations. Few days later, I received an email with the bill, which was very reasonable, and so far my heating system is working like a champ. It is nice to know that there are still good and honest people in this world."

Install Boiler FAQs, answered by experts

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

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.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.
