For commercial installations, the product warranties adjust to three years. This reflects the more demanding usage conditions that commercial systems typically face.
Beyond the warranty, Thermann also offers a 12-month coverage for spare parts and labour for both commercial and domestic systems. This is provided the installation and usage adhere to the terms outlined in the Owner’s Manual. Coupled with Thermann’s excellent after-sales service, it’s safe to say that the brand is dedicated to ensuring customer satisfaction long after the initial purchase.
Pricing and Value for Money
Known for its affordable initial purchase cost, the Thermann 250L electric hot water system is a viable option for many consumers in the hot water market. However, the affordability doesn’t stop at the initial purchase.
The Thermann 250L system offers:
-
Potential for significant cost savings through the use of lower electricity tariffs during off-peak times
-
Considerable reduction in running expenses
-
Long-term value for money
In terms of quantifying the cost, the average cost for supply and installation of the Thermann 250L electric hot water system in the Sydney area is approximately $1,700.00, excluding additional necessary components. An extra investment of around $200.00 is necessary for a tempering valve, which is mandatory by law for the installation of hot water systems like the Thermann 250L. Prices can vary depending on the specifics of the installation and the location, making on-site assessments crucial for accurate costing.
Customization Options for Your Thermann 250L
The Thermann 250L electric hot water system features dual-handed water connections, a convenient feature for homeowners seeking to upgrade or replace their existing electric hot water unit. This provides the flexibility to easily replace and upgrade from any existing branded electric system, ensuring you can efficiently heat water in your home with storage hot water systems.
This feature, coupled with the fact that the Thermann 250L system has an identical electrical footprint to previous models, makes it a convenient and flexible choice for homeowners looking to switch to a more efficient and reliable hot water system with an easy changeover manufactured.
Comparing the Thermann 250L to Other Models in the Range
Compared to other models in the range, the Thermann 250L model is evidently designed to cater to medium-sized households consisting of 3 to 5 people. This sets it apart from smaller models like the 135L, which cater to fewer users.
The Thermann 250L offers various hard water element options, including a twin-element design, with different element sizes for different recovery rates. This provides recovery rates ranging from 31L/h at a 50°C rise for the 1.8kW element to 83L/h for the 4.8kW element.
However, it’s worth noting that using the Thermann 250L on an off-peak tariff may lead to instances where hot water runs out during heavy usage days and will not reheat until the off-peak period overnight.
Enhancing Your Home's Hot Water System with Thermann Technology
The Thermann 250L system provides hot water at mains pressure through a continuous flow mechanism. This means multiple taps can be used simultaneously without a drop in pressure, a feature that can significantly enhance the comfort and convenience of your home’s hot water system.
The system’s heating efficiency is influenced by the variable element recovery rates, ensuring optimal usage and energy conservation. Furthermore, the Thermann 250L system is designed for energy efficiency, potentially reducing energy expenditures and environmental impact.
For homes with an existing photovoltaic (PV) system, the Thermann 250L can be linked to harness solar energy for heating water. This integration provides a consistent hot water supply, even in overcast conditions, and further reduces electricity costs.
Maintenance Tips for Your Thermann 250L Electric Hot Water System
Regular maintenance is critical for the Thermann 250L Electric Hot Water System to function efficiently and last long. One of the first things to pay attention to is the thermostat. Periodically checking the thermostat is crucial for accurate temperature regulation.
Another component to keep an eye on is the pressure relief valve in art machinery. Regular inspections of this part are necessary to prevent dangerous pressure buildup and ensure the system operates safely.
Lastly, regular cleaning of the tank helps to prevent sediment buildup, which can impair the system’s efficiency and reduce its lifespan. An annual flush of the tank contributes to removing sediment, assisting in maintaining the Thermann 250L’s efficiency.
Summary
In summary, the Thermann 250L Electric Hot Water System is a robust, efficient and affordable choice for medium-sized households. With its ample storage capacity, durability, and potential for energy savings, it offers excellent value for money. Additionally, its compatibility with solar energy and simple maintenance requirements make it a reliable and economical option for ensuring a steady supply of hot water in your home.
