"Worst service I’ve ever have experienced. They wanted to sell me the product, never told me that there was an early termination fee and another penalty for an initial offer they gave me. Had double charges every month, once for the oil they provided (which they never told me they were going to provide before coming. They just came without my knowledge and then I find a high amount bill) and another for an “automatic payment” for 500 that they never could explain. The didn’t even fix this issue and it kept happening every month even after I cancelled the service. Then having to call them is a hastié for the refund of the 500. Stay away of this company"

We are a family owned business and specialize in Water heater installation, removal, and repair for all manufacturers and models. We do everything water heater related including pressure reducing valves, thermal expansion tanks, water shut off valves, leak repair etc. Promised to be quick in responce, fast, efficient and knowledgeable. Over 13 years of experience in the field.

"Wow, blown away by the work Jeff and Water Heaters in a Hurry did. I am stunned by the professionalism, honesty and transparency, the depth of their skill and knowledge, and the downright far more than reasonable charge for their service. I had a tankless water heater replaced. It took me weeks until I got to Jeff and WHIAH, so many people gave me the runaround, not following through even on a quote, suggesting absurd costs like $3K+ for labor. Why's it so hard to find someone honest, dependable, professional, and competent these days? As soon as I was in contact with Jeff, a huge weight came off my shoulders because I knew I was now in the right hands. Empathic, knowledgeable, patient and transparent... and fast! When they installed, they identified and rectified many mistakes made by the person who installed the last one 5 years ago. They thoroughly checked the work when done, even safety checks. The labor cost was half the high end of others. HIRE THESE GUYS!!!!!!!!!!!!! Trust me."

Boiler Repair questions, answered by experts

Blockages can occur for various reasons, primarily linked to the accumulation of debris or substances within the heating system. Common causes include the buildup of sediment, rust, or mineral deposits inside the boiler or its pipes, hindering water flow and heat transfer. Additionally, air pockets or trapped gasses can impede circulation. In central heating systems, sludge or corrosion within radiators can obstruct the flow of hot water. External factors like frozen pipes in winter can also lead to blockages. Regular maintenance will help prevent blockages and ensure efficient boiler operation.

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

The difference between a heat pump and a boiler is simple. A boiler often works with a furnace as part of a heating system. Some HVAC systems also have an AC to cool the home in addition to a boiler. A heat pump is unique as it works as both a heating and cooling system, altering ambient air to a comfortable indoor temperature.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

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.
