The Benefits of Tankless Water Heaters

There are so many benefits to making the switch from a tank to a tankless unit, such as:

  • Tankless water heaters work by heating your water as it travels through the pipe. Cold water comes from the pipe into your water heater and then hot water gets delivered to your shower, faucet, or appliance. Since there’s no tank, they take up significantly less space. They can be mounted right to the wall, so they’re tucked away in your utility room.
  • Tankless water heaters also use much less energy. Unlike water heaters with tanks, they don’t waste energy heating and reheating water throughout the day. Instead, they deliver hot water as you need it. This can save you significantly on energy costs.

As trusted Houston plumbing experts, we’ve installed countless tankless water heaters and can install one for your home, too. We’ll even recommend which water heater to choose based on your specific situation. Whether you’re running several loads of laundry and dishes a day or just want to be able to take a nice, hot shower after a long day, we’ve got solutions for you.

Tankless Water Heater Repair

Tankless water heaters are a popular choice in Houston and many other areas due to their energy efficiency and space-saving benefits. However, like any appliance, they can occasionally require repair to ensure they continue to function at their best. If you're facing issues with your tankless water heater in Houston, it's essential to understand the importance of timely repairs and the professionals available to assist you.

Common Tankless Water Heater Issues:

  • Lack of Hot Water: If you're experiencing inconsistent hot water or none at all, it could be due to mineral buildup, a malfunctioning heating element, or a blocked vent.
  • Fluctuating Water Temperature: Fluctuations in water temperature might be caused by an improper gas supply, an issue with the thermostat, or a flow rate problem.
  • Ignition Problems: Failure to ignite can stem from issues with the gas supply, ignition components, or a ventilation problem.
  • Strange Noises: Unusual noises such as popping or rumbling may indicate mineral buildup within the unit.
  • Error Codes: Tankless water heaters often have diagnostic error codes that can help pinpoint the problem.

Regular maintenance and timely repairs can extend the life of your tankless water heater, ensuring that you continue to enjoy the benefits of energy efficiency and on-demand hot water in your Houston home. If you encounter issues with your tankless water heater, don't hesitate to reach out to Santhoff Plumbing for a swift resolution.

Electric or Gas Water Heater: Which Is Better?

Tankless water heaters can be powered by electricity or natural gas. Our experts offer tankless water heater installation in Houston for both electric and gas options.

Electric tankless water heaters tend to be less expensive than gas, however electricity typically costs much more than natural gas. So, even though tankless water heaters are ultra energy efficient, you might end up paying more to operate your electric water heater in the long run.

Gas tankless water heaters usually cost more up front but offer long-term savings because natural gas is typically much less expensive than electricity. If you want to reap the benefits of these long-term savings, our gas specialists can install natural gas lines for your new water heater or connect it to your existing lines.

When is it Time to Install a New Tankless Water Heater?

Deciding when to install a new tankless water heater depends on various factors. Here are some common situations in which you might consider replacing or installing a new tankless water heater:

  • Age of the Current Water Heater: If your existing tankless water heater is reaching the end of its expected lifespan (typically around 10-20 years, depending on the model and usage), it may be more cost-effective to replace it rather than continue with repairs.
  • Frequent Repairs: If your current tankless water heater requires frequent repairs, and the cost of fixing it is becoming prohibitive, it may be more economical to invest in a new unit.
  • Insufficient Hot Water: If you're experiencing a decline in the amount of hot water your tankless water heater provides, or if it's struggling to meet your household's demand, it might be time for an upgrade.
  • Changes in Household Size or Water Usage: If there have been changes in your household, such as an increase in the number of occupants or changes in water usage patterns, you may need a larger capacity tankless water heater to meet the new demand.
  • Technological Advances: Advancements in technology may offer more energy-efficient and feature-rich tankless water heaters. If your current unit is outdated, upgrading to a more efficient model could save you money in the long run.
  • Energy Efficiency Considerations: If you are looking to reduce energy consumption and lower utility bills, newer tankless water heaters are often more energy-efficient than older models.
  • End-of-Life Signs: Signs of corrosion, leaks, or other structural issues in your current tankless water heater may indicate that it's at the end of its useful life.
  • Government Incentives: Check for any government incentives or rebates for upgrading to a more energy-efficient water heater. This could help offset the initial cost of a new tankless system.
  • Planned Renovations or Upgrades: If you're planning major renovations or upgrades to your home, it might be a convenient time to install a new tankless water heater.

Before making a decision, it's advisable to consult with a professional plumber or HVAC technician who can assess your specific situation and provide guidance on whether installing a new tankless water heater is the best course of action. They can consider factors such as your hot water needs, the condition of your current system, and the available options in the market.
