Frequently Asked Questions - ASA 800-1 Baxi

What is an inertia accumulator used for?

An inertia accumulator stores thermal energy to reduce boiler cycling, improve system efficiency, and provide consistent heating or hot water.

How do I install the Baxi ASA 800-1?

Place on a level, load-bearing floor. Connect to the heating system using the 1" BSP connections. Ensure a pressure relief valve and expansion vessel are installed per local regulations.

What is the maximum temperature of this tank?

The maximum operating temperature is 95°C (203°F). Do not exceed this to avoid damage.

How often should I maintain the tank?

Inspect the anode rod annually and replace if consumed. Check the pressure relief valve annually. Drain and flush every 2-3 years.

Can I use the ASA 800-1 with a solar thermal system?

Yes, it is compatible with solar thermal systems. Use an appropriate heat exchanger and ensure fluid temperatures stay within limits.

What is the weight of the tank when full?

When full, the tank weighs approximately 950 kg (800 liters of water + 150 kg tank weight). Ensure floor can support this load.

Does the tank come with insulation?

Yes, it includes 100 mm polyurethane foam insulation to minimize heat loss.

How do I drain the tank?

Turn off the system and let water cool. Connect a hose to the drain valve at the bottom. Open the vent at the top and drain.

What happens if the pressure relief valve discharges?

It indicates overpressure. Check if the expansion vessel is faulty or if the system temperature is too high. Contact a professional if repeated.

Where can I find spare parts?

Contact Baxi authorized dealers or parts distributors. Common spare parts include the anode rod, thermostat, and relief valve.
