My water heater (30-gallon, gas) has reached the end of its

Hello,My water heater (30-gallon, gas) has reached the end of its useful life. I'm considering my options, but I have a fairly specific situation.My partner and I live in a loft-style condo in San Francisco, with the bedroom on the second floor, open air style (no windows to the outside). My water heater is in a closet in the bedroom. Although the exhaust is pumped outside of my building, the ambient heat tends to stay in my bedroom and cause it to get hot, which is annoying in the summertime. I would like to buy a water heater that solves this problem. Will an electric water heater or a tankless water heater solve this problem? Are there other options that will help solve this?Thank you!

I had the heat exchanger replace because it was blocked by corrosion. I'd like to clean out the old one. I've tried to do it with vinegar, but it is still blocked. What can I use? CLR says it should not be used on copper or brass.JA: Sometimes HVAC issues that that you think will be really complicated end up being easy to fix. The HVAC Technician I'm going to connect you with knows all the tricks and shortcuts. Is there anything else the HVAC Technician should be aware of?Customer: I have installed a water conditioner to reduce the problem; the first charge on the conditioner lasted about six years.JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the HVAC Technician about your situation and then connect you two.

Replacing a Gas/Steam Boiler (cracked). House is 4 stories,

Replacing a Gas/Steam Boiler (cracked). House is 4 stories, 4390 SF with Steam Radiators (standing and baseboard) and some vents. Built in 1895, has relatively poor insulation. HomeServe cane and measured the Radiators to Spec the Boiler. Recommended an IN-6 (175K BTU) to replace the failing (35 year old) Utica (263K BTU). I have 3 questions regarding this transaction. I welcome your informed opinion.1) Sizing: ONLY the radiators were measured for the sizing. I am concerned about the discrepancy of the old 263K BTU with the newly specced 175K BTU, especially in view of the poor insulation (difficult to remediate) and the large (4390 SF) house. Do you think it is possible that this is correct and should I be concerned?2) Reliability: I have found many questionable reviews of the Burnham Independence Series online. Do you think this line is a good choice for quality, longevity, warranty, etc? Do you have alternate brand that you like better?3. Cost: The IN-6 sells @ supplyhouse.com for $3500. They quoted me $8145. That works out to $4645 Labor (and ancillary parts). Hard to see how a one day install could cost $4645 at ANY reasonable hourly rate. Please comment.Glad to answer any followup questions that you may have.

Just installed a honeywell wifi thermostat with a remote

Hi, Just installed a honeywell wifi thermostat with a remote sensor. The sensor is on second floor and thermostat in basement. I have it set to 68 and havent seen the temp. drop below that. It always shows 68. The problem is the boiler keeps on cycling on and off very often around every 5-7 minutes. Im worried about ruining the boiler with all the cycling. Thanks
